What does a persons stuff tell you?The big questions
What possessions, preferences, etc., tell you what a person is like?Do they tell you anything at all?Why might they be useful?
People have beliefs about stuffAnd what it can reveal about a personPeople make judgments based on a persons musical tastes (Rentfrow & Gosling, 2009)People believe that messy people are lower in A & C but higher in O & N (Harris & Sachau, 2005)People draw inferences from a persons appearance and clothing (Bardack & McAndrew, 1985)People believe that dogs look like their owners (Roy & Christenfeld, 2004)And so on
People have beliefs about stuff
Do dogs look like their owners?Yes! To some extentParticipants were asked to try to pair up pictures of dogs and their owners taken at dog parksParticipants did better than chanceWhen they judged purebredsBut not when they judged muttsPeople can choose dogs that look like them
Other look-alikesAlpers et al, 2006
Look-alikesResearchers went to a rest stop, and took pictures of 60 drivers and their cars, separatelyParticipants attempted to match pictures of cars with pictures of owners68% of the cars were reliably paired with their owners
Implicit egotismPeople like to think positively themselves, and do so automaticallyThese feelings influence them to think positively about things simply associated the selfThis happens at a very basic levelThe name letter effect: People like the letters that are in their name more than the letters that are not (same goes for the numbers in their birthdays)And for more complicated things, too
Implicit egotismHalf Ps partners had a code # that was the Ps birthdayHow much do you look forward to getting to know the partner?How much do you think you would like this person?

Implicit egotism and brandsPeople like products whose brand names start with their initialsStage 1: Implicit egotism (the underlying motive to self-enhance) endows the name letters with positive valenceStage 2: The positive valence gets endowed to the product attributes themselves

Online personalityThree questions about websites (or any item that might convey personality):1. Do personal websites convey a coherent message about the owner? (Consensus)2. Is the message conveyed by websites accurate? (Accuracy)3. Is the message conveyed by websites overly positive? (Impression management)Vazire & Gosling, 2004
Online personalityThe answers to the questions are1. Consensus: Yes! People do agree on the personality of the owner of a website2. Accuracy: Yes! People can be quite accurate at gauging personality from a websiteeven an individual person is often accurateOpenness is the easiest trait to distinguishNot due to sex or age stereotypes3. Impression management: Yes! People do emphasize more flattering aspects of their personalityExtraversion and agreeableness tend to be enhanced

What causes what?The data by nature is correlationalDo personalities cause certain preferences?Do preferences lead to personalities?Is there a third factor?An intervening factor (a moderator)?
Can you spot a poseur?Three categories of personality clues:
Category 1: Easiest to manipulate. These are deliberate signals, where the signal is the goal of the clue. Ex. Bumper stickersCategory 2: In the middle. These are deliberate modifications of your environment, but signaling is not the purpose. Ex. Creating a comfortable living spaceCategory 3: Hardest to manipulate. These are inadvertent signals, byproducts of our behavior. Ex. Dirty dishes in the sink
Controllability of impressions
