(New Yorker) - internal and external
Kelley's
Theory of Attributions - One of my fellow managers came to me
today with a complaint about the performance of one of my subordinates.
They had been in a meeting together where Tony (my subordinate)
had acted very surly and obstinate about a new process we were trying
to implement. John (my peer) made the comment to me that "Tony
sure is an uncooperative person. You need to straighten out his
attitude." I asked John if Tony was the only one to act in
that manner. John replied that most others in the meeting were upset
but Tony just happened to be the worst. My next thought was that
Tony is usually pretty easy going and has never been upset when
we've implemented a new procedure. I asked John whether he'd ever
seen Tony get upset at any other meetings and John replied that
he hadn't. By using Kelley's model and considering consensus, consistency,
and distinctiveness, we concluded that Tony was acting in an uncharacteristic
manner and must be upset about the new procedures (an external cause).
The saleswoman got really excited the other night when Kevin (19
months old) waved bye-bye and smiled at her. She probably thought
that Kevin really liked her and that his behavior was highly distinctive.
I know that he is consistent in waving and smiling, and this was
not reserved especially for her. I doubt that all babies
wave and smile at everyone, so that would not be a consensus.
Fundamental Attribution
Error - I let my students know that I regularly exhibit the
errors and biases we discuss in class, and none is easier than the
FAE. So, I'm in a fast food restaurant when I decide I need to use
the bathroom. The door to the single-user bathroom is closed. Is
anybody in there? I try the doorknob to find out. It is unlocked,
so I proceed to enter. A man, with his back to me, fortunately,
is at the urinal. I exit and close the door. Enter the FAE. Why
wouldn't he lock the door? What kind of guy is he? I am not just
led to negative attributions; I also consider that he is comfortable
enough with himself that he is not embarrassed.
You probably know where this is going. As I take my turn in the
bathroom I notice that the lock is broken on the door. And as I
continue to use the bathroom, another person opens the door only
to find it occupied. I wonder what he was thinking? And why didn't
I or the previous occupant tell the next person that the lock was
broken? [added 9/23/07]
Fundamental
Attribution Error - Today, I was stopped at a red light. At
one point, I edged my car forward slightly. Immediately after I
did this, the man next to me (in his very sporty, turbo, fancy car
of some sort) edged forward also. I, at once, thought to myself,
"What a jerk, he just doesn't want me to get ahead of him when
the light turns green." At this point, I realized that I wasn't
taking this man's perspective and that I was making a fundamental
attribution error. Perhaps my movement forward made him think the
light was green, or perhaps he was just tired of having his foot
on the brake like I was.
Unfortunately,
our new apartment is not completely sound-proof. My husband and
I can easily hear the person above us. We have never met the person
but we already have preconceived ideas about who she is,
what she does, and what her attitudes are. Last night,
she came home very late and right away Bruce starts going on about
what a tramp she must be for staying out so late. He constantly
makes fundamental attribution errors about this person above us.
Since we have never met her, we cannot possibly take her actual
perspective of things. However, we could give her the benefit of
the doubt. Who knows, maybe her car broke down or she was on vacation
and her plane came in late. Although we don't know her and we probably
shouldn't think things about her without even meeting her, it's
fun to make up ideas about who the person upstairs really is.
Fundamental Attribution Error - I tell my students of how I
used to drive into a gas station and get upset at another driver
whose car was sitting at the second pump in an aisle while there
was no car at the first pump. "What an idiot. Why didn't he/she
just pull up to the first pump?" Of course, it usually hit
me that perhaps there had been a car at the first pump when this
driver pulled in. I no longer jump to the conclusion that the driver
is an idiot, so I also use this as an example of how it is possible
to control this error. We discuss how difficult that is.
Self-serving
Bias

Jantelagen - Eric Hansen, from Sweden, passed along this example:
"The Swedes have a phenomenon (or in this case sort of a norm)
they call Jantelagen (pronounced Yanta lagen). I think it comes
originally from Denmark. I myself am a US citizen who moved to Sweden
in 1997, so I do not have Swedish culture as my own, which is probably
both an advantage and a disadvantage. I probably notice things my
colleagues don't, but don't have the background to understand them
as fully they would once I recognize them. Anyway, this Jantelagen,
which I believe means Jante's law can be interpreted as a strong
norm against extolling one's virtues and achievements.
One
of my students once sent me the following "satirical"
10 commandments related to Jantelagen: taken from a source I could
probably find. I believe it is a book called En flykting kryssar
sitt spor (1933) by Aksel Sandmose.
Below
is a direct translation of what they mean, in some cases with my
interpretation in parentheses.
Jantelagen (10 satiriska budord) - Jantelagen 10 satirical commandments
1. Du skall icke tro att du är något. -- You (thou) shall
not believe that you are something. (You should not believe you
are something special)
2.
Du skall icke tro, att du är lika god som vi. -- You shall
not believe that you're as good as we are.
3.

8.
Du skall icke skratta åt oss. -- You shall not laugh at us.
9.
Du skall icke tro, att någon bryr sig om dig. -- You shall
not think anyone cares about you. (an interesting aside, there was
recently a giant hit song with the chorus nobody cares where you
bought your sweater, I know it doesn't translate so well, but the
point they were trying to make in the song was that you're not as
important as you think).
10.
Du skall icke tro, att du kan lära oss något. -- You shall not believe
you can teach us anything.
Based
on this "law" I am currently running a study in collaboration
with a colleague in the States which makes a cross-cultural comparison
of the self-serving bias. The idea is that Swedes are less likely
to extol their virtues than Americans, unless permitted to do so
anonymously. I view it as a type of false modesty, meaning I think
Swedes privately think they are better than other people, but are
loathe to talk about it publicly. I have some preliminary data that
show significant differences in estimates of oneself compared to
estimates of the "average other" in Swedes when ratings
are made anonymously. In a follow up (being run now) I am investigating
what happens when ratings are made publicly." [added

Cartoon
(New Yorker) - inflated group perception
We
had a golf meet yesterday. I played terribly. It was my worst round
in like three or four years. Naturally, I was a CLASSIC case
study of self-serving bias. I came up with every excuse in the book
to explain why I played so poorly. It was raining; it was the first
time I ever played that course; I had a couple of bad holes; the
list goes on and on. I attributed my failure on a hundred external
factors, but none on me. I couldn't understand why I played so poorly,
so there must have been some causes. I never play that bad, so I
tried to find reasons. Well, there's always tomorrow ... My
first experience with writing options in the securities market was
a great success. Not only was it profitable, but I managed to sell
and buy at the precise high and low points thereby confirming my
belief that I was exceptionally good at this. I was soon projecting
how my profits would grow over the next few years. The
results that followed were not as impressive. A mix of smaller wins
and losses did not change my beliefs. There were always explanations
that could take me off the hook and place the blame on some
external circumstances that which were temporary and unusual. Essentially
the small losses were written off as flukes, and the small wins
were seen as a direct result of my skill; they would have been even
larger had so many things not turned against me. The self serving
bias (wanting to see myself as a skilled trader) and the illusion
of control (believing all the wins were a result of my good judgement)
were at work here. It was not until a substantial one time loss
occurred that I began to objectively evaluate my performance. The
dissonance between my beliefs and what was occurring became too
great to rationalize away.

Primacy
Effect - I had an interesting experience with a fellow supervisor
yesterday. An employee had recently promoted out of my department
into his and it was about time for him to give her a 30-day review.
I asked him how she was doing. He said not too well but that he
really hadn't expected much from her. This surprised me because
she had been a very good worker for me. I asked him why. He said
that judging from the size of her personnel file I had passed along
to him he was sure he was going to have problems with her performance.
I asked if he had read the file. He said no, he hadn't wanted to
bias his opinion of her before his first review. I guess the Rosenthal
effect is at work here because he had in fact made his "biased"
judgment based on file size. If he had taken the time to read through
the file he would have seen that it was full of extra training documentation
and notes of commendation on work performance. This had been an
employee who for me had shown much initiative and continually came
up with problem solutions.

Vividness
Effect/Availability Heuristic - "Baseball is a game
of inches." That statement is frequently heard in baseball
(and similar statements are often made in other sports). It only
seems that way though because we most vividly remember the close
calls and close plays. Usually the ball goes several feet or yards
foul or over the fence or the runner is safe by several feet. It
doesn't sound as good though to say "Baseball is a game of
feet." [added 7/21/03]

Vividness
Effect/Availability Heuristic - Had a good guest speaker in
this week to talk about quality and customer service. His very first
point in describing how to provide memorable service was to provide
the customer with a "vivid" example so they always remember
and associate your company with that. For instance, I was recently
out of town, stopped in a store for a bottle of aspirin; went to
the check out counter and found the price was not tagged on the
item. The clerk turned to the manager walking by and asked for the
price. The manager turned back to me and said, "Please accept
this at no charge. This is an administrative management problem
and not yours. We should have had it marked and I don't want to
hold you up any longer. Sorry for the inconvenience, please come
back." Was I stunned! But, as a customer I will always remember
my positive experience and that vivid example will override most
negatives which might occur.
Vividness Effect/Availability Heuristic - I saw the movie "Witness"
last night in which Harrison Ford plays a Philadelphia cop who lives
among the Amish for a short period. A strong outgroup bias was evident
among the Amish. Some of them didn't accept him because he was an
"Englishman." Most likely, they had encountered some other
non-Amish people who behaved in a manner that wasn't acceptable
to them, and they had these same feelings toward Harrison Ford initially.
They had these same feelings about the woman who brought Harrison
Ford to live in their community, and there was a lot of gossip about,
and hostility toward, the two of them. After the community got to
know Harrison Ford as a man rather than an "Englishman,"
they accepted him. One day Ford went to town with a group of Amish
people. He was dressed like the rest of them. The people in town
were accustomed to their pacifist ways, so they were quite surprised
when Ford got into a fight with some bullies and won. The Amish
excused him as being a cousin from Ohio. From then on, I'm sure
the Ohio Amish had a bad name in Pennsylvania. This vividness effect
would be used to make judgments about the Ohio Amish. Ford was hiding
out from the Philadelphia police and didn't want his picture taken.
So when a tourist woman insisted on taking his picture, Ford replied,
"You take my picture and I'll rip out your brassiere and strangle
you with it!" Obviously, the woman didn't take his picture.
This unusual behavior (vividness effect) would probably cause the
woman to have negative feelings about all Amish people. Ford was
not really an Amish,but the woman's perception of reality was that
he was. For her, Amish people are probably stereotyped as nasty.

Names
- I hate the name Marvin. I've always hated the name. It doesn't
sound masculine. It sounds like his mother must have hated him.
When I hear it, my schema says "spoiled brat." In my mind,
there are no good cognitions associated with the name. Since I never
knew a Marvin when I was growing up, I don't know why I have such
strong feelings about the name. If anyone would have told me that
someday I would be married to a Marvin, I would have told them they
were off their rocker. But that's exactly what happened. However,
I still dislike the name so much, that sometimes my mind refuses
to let my mouth say it. I can't tell you how many times I've slipped
and called him Norman. I have never dated a Norman, so I don't know
why my mind insists on substituting that name, but it does. As you
can imagine, my husband fails to see any humor in this. At any rate,
my husband is a very kind and generous man. He is not at all like
the schema that I continue to associate with his name. In order
to maintain a feeling of consistency, and to relieve dissonance
regarding the conflict between my attitude and actions, I've convinced
myself that my husband is an exception to the rule.
Names
- Talk about preconceived notions -- the other night I met one of
my friends for a drink that I hadn't seen in a long time so we had
to do a lot of catching up. Well, it turns out that my friend is
dating a man named Gus. Gus is supposed to be very nice and distinguished
looking. The whole time my friend was telling me how great he was
all I could do is smile. She finally asked me what was wrong. I
replied nothing but all I could think of was that Gus was a donkey
(jackass). Now I had never met this man but I associated the name
with the only Gus I have encountered. Gus was a donkey on a Walt
Disney movie who kicked field goals. Since this was the only Gus
I knew I was having extreme difficulty with the word "distinguished."
It did not fit into my implicit personably tract. If she had said
"unique," maybe even "winning," there might
have been a connection of sorts.
Professions
- When the news flash came on television describing Peter Fonda's
stealing of a limousine in Chicago and being subsequently let go,
my mind seized upon my "actor/actress schema!" I remarked
to my husband: "How typical, only an actor could try something
so arrogant and get away with it." I was referring to the schema
with which I associate actors and actresses: snobbish, self-serving
people who consider themselves to be above the law, above other
people and exceptions to almost any rule. My schema also considers
actors and actresses to have "overly-large egos" and lots
of plastic surgery.
Professions
- We went sightseeing in Vancouver using their transit system to
get around. I was thoroughly impressed with Vancouver and even more
so with their transit system and the people. The bus, train, and
seabus are part of the same network. For a three dollar (Can. $)
day pass, you can go anywhere, anytime by one of the three systems.
The amazing thing for me was the bus drivers. They did not fit the
schema of a bus driver. They had neat appearances, were friendly,
and even thanked you when you left the bus. It was a sharp contrast
to the image of the gun-carrying Chicago CTA driver. The extreme
contrast to my negative image of drivers probably made them appear
more friendly and helpful than they actually were. Had I not been
from the Chicago area, I wonder if I'd have been so impressed.
Gender
- One example which I have used in my journal entry earlier this
term is my relationships with my female boss. Although I like to
consider myself a non-prejudicial individual I find myself looking
at gender stereotypes when I consider her management techniques.
I have found her to be very moody and unpredictable. Because neither
of my former supervisors at this corporation (who happened to be
male) did not show any evidence of "mood management" I
have drawn a conclusion that it is because of her gender. This is
unfair and an antiquated view to hold but to be honest I have yet
been able to shake this stereotypical view of her.
Gender
- I witnessed and participated in two situations where gender-role
stereotypes were brought out. My son plays on a traveling soccer
team. It is a team for his age group and they play against teams
from other towns around northern Illinois. We have traveled from
Orland Park to the southeast to Rockford to the west. The kids on
these traveling teams are supposed to be the best players of their
age from the areas they live in. Last week the team my son played
against had a female player. She happened to be the other team's
best defensive player. It was interesting hearing the parents of
the players on my son's team yell at their sons for not being able
to get past that girl. They made statements like "She's only
a girl, you must be able to beat her." What was most interesting
was that most of the comments were made by mothers -- not fathers.
Religion
- Before I married and assumed a Jewish name, I did not realize
that the prejudice would be so strong. We are resented almost everywhere
we go. It began with my friends. Shortly after we were married,
they began to fall away. Even my children from my previous marriage
feel uncomfortable around my husband, just simply because he's Jewish.
My former in-laws act as if I died. They never ask the children
about me and quickly change the subject if one of them mentions
my name. Then
there's the clerks in stores when they see my name (obviously Jewish)
on my credit cards. We're all supposed to be rich, spoiled princesses.
Our husbands got rich through unscrupulous business practices. Sometimes
they can be very surly. The churches are not much better. They see
us as Christ killers and the word "Jew" definitely bears
a negative connotation. It's either hurled from the pulpit or whispered
in private. I
say "we" rather loosely because I'm a Christian and attend
church regularly. I'm also a member of a synagogue, that I attend
infrequently with my husband. I've heard a lot of snide remarks
and I've learned a lot about how these people cope. They're not
perfect, but I don't know anyone who is. There's a lot of truth
in that old saying about walking in someone's shoes before you judge
them. I've been doing it for several years now and I have quite
a different perspective. Unfortunately, as long as stereotypes are
perpetuated from generation to generation, few people will ever
view life through a Jew's eyes and the prejudice will continue.

False consensus effect - The other day my friend exhibited the most blatant false consensus effect I've ever heard (and recognized). I don't know how we got on the subject, but we started talking about things that lots of people do but rarely acknowledge. She said, "Yeah, like when you're sitting alone in your house or something and you can imagine where you'd go and what you'd do if a robber came in!" I simply responded with a vacant stare. She replied, "What, doesn't everyone do that?" Apparently not. Later, she still claimed that lots of people do it. Double whammy: False consensus effect and belief perseverance all in one go. [Editor's note: Who was actually exhibiting the false consensus effect?] [added 4/16/08]
False consensus effect - Every single Saturday morning was dedicated to cleaning the house throughout my childhood. This was designated by my parents and we would each receive chores or a specific set of tasks that we were required to do around the house. I remember one time a friend asking me to come over to her house for a play date on a Saturday morning. I became confused, however, because I assumed that her family would participate in the same Saturday morning cleaning routine and asked if I had to help her clean if I came over. This is an example of the false consensus effect because I believed that others shared the same schedule that I did more than they actually did and was shocked to learn that not all families cleaned on Saturday mornings.

whom to ask to the homecoming dance. One day he would come home

he decided to ask Jessica instead. Before bedtime he had decided
to ask Sara. I think he was afraid of being turned down and just
couldn't decide who was the best bet and least likely to turn him
down. Finally he came home from school one day and announced he
had asked Jessica to the homecoming dance. My wife immediately said
"I just knew all the time she'd be the one you would ask. I
would have bet money on it." If she was so sure why didn't
she offer to bet. This appears to be the old I-knew-it-all-along

Illusion
of Causation - When I drive to work, or for that matter, when
I go anywhere and I'm in a hurry and worried that I will be late,
I have a sure fire way to improve my chances of being on time. In
order to put on lipstick I have to be at a red light, but every
time I want to put on lipstick the traffic signals always
seem to stay green. So if I am in a hurry, I always take out my
lipstick because I know if I do this it will cause all of the traffic
lights to be green! Is this wierd or what! I guess the "what"
is illusory causation.
Illusion
of Causation -- My parents have been trying to sell their house
with little success. My mother finally gave into an old Catholic
superstition. She buried St. Joseph (statue - of course)
upside-down in the backyard! No, they have not sold it yet -- but
she is waiting!
Illusion
of Causation - There have been a number of times my family has
received extra funds just so the car could break down. My records
confirm that whenever we receive any extra cash such as tax returns,
insurance settlements, even loans, one of our automobiles breaks
down within a predictable interval of time. An interval that always
requires a commitment of some of the newly acquired cash.
Illusion
of Causation - I found myself half-believing two illusions of
causation earlier this week. This is our third home. The first two
homes both were sold the year after we built a deck in the back
yard. This year we built a deck in the back yard of this third house.
I told my husband that we'll be moving next year for sure. Building
decks causes us to move. This leads on to my second illusion of
causation. We have lived in three houses and I have gone through
three pregnancies -- one pregnancy in each house. Therefore, since
we are going to move next year, I will also be getting pregnant
next year. Moving into a new house causes me to get pregnant.
Then
again, perhaps I could combine the two illusions into one and just
state that building decks cause pregnancies. I know none of this
is true, that it's all merely coincidence. (At least, I hope it
is.)
Memory Distortion/Reconstruction - "For
me I think the point of 'Peggy Sue' is how memory often lies. Peggy
Sue is bitter that her husband left her for another woman. She's
bitter about that, and she has built it up in her mind that he never
loved her. But she goes back in time and she rediscovers that he
really did love her. Her memory is disturbed in a valuable way by
the experience. The point is that for a lot of the things we believe
about our life, it would be a good idea to go back and check the
facts." I found the above comments in a movie review. This
reminded me of material that we covered about memory. Here is a
good example of how the facts got distorted over time. Not all of
us can go back in time, in fact, none of us. But if we did, I think
we'd find the facts of the past different from the opinions we've
created today. Some would have greater differences than others but
very few would be exactly.
Overconfidence in clinical judgments - Interesting case of a man exonerated on DNA evidence. He had been convicted 21 years earlier solely on the testimony of a criminal profiler. [added 5/3/08]
Self-fulfilling
prophecy - Listen to this interesting story of a mother who
raised her son with Mosaic Down Syndrome without telling him or
others around him that he had the disorder. Hear in this 13 minute
story how not knowing about the disorder led to a variety of mostly
positive interactions and interpretations of her son. To find the
episode, go into the episode archives on the left frame and click
"06" for 2006. Then scroll down and find episode 311 ("A
better mousetrap"). Six minutes/32 seconds into Episode 311
is where this story begins. Thanks to Harry Wallace for pointing
me to this resource. [added 12/29/06]
Self-fulfilling
prophecy? - "Athletes abstain from sex in quest for gold"-
Illusion of causation? Confirmation bias? Or...the truth! "Team
USA doctors say that there is no proof that abstaining from sex
helps athletes gain an edge." On the other hand, gold medalist
Chad Hedrick says, "I tried, and it is working so far, and
I am going to continue doing it until I accomplish all my goals."

Decision-making
Priming
and Context - Imagine you are told you will be drinking wine
from California or... from North Dakota. Sure, you might prefer
the California wine (even though it's the same), but you also say
the food you are eating tastes better. [added 9/23/07]
Bounded
rationality - This paper addresses the divergent concerns about
terrorism and climate change: "The United States has responded
aggressively to the risk of terrorism while doing very little about
the risk of climate change." Explained in terms of bounded
rationality. [added 7/5/06]
Is
more choice better for decision-making?
- an OpEd piece from Barry Schwartz in which he refers to research
on choice in decision-making to analyze Bush's social security privitization
proposal [added 3/20/05]
Heuristics
- neat, simple, interactive online example of heuristics and cognitive
load from Don Forsyth [added 3/6/02]
