Two new studies shed light on relationships and friendship.
The first new study was published in Personality and Social Psychology Bulletin.
The study recorded people in different situations, like asking a neighbor to turn down their music. That video was then shown to strangers, and friends, who had to judge the participant's behavior.
According to the study's findings, we judge people we know to match our specific impressions of them. For example, if we think of someone as generally talkative, we will judge that person to be more talkative in specific situations beyond what a stranger would see in the very same behavior.
"We really like to have our images of persons be consistent," the researchers added. "This is probably beneficial in terms of arriving at an overall image that is representative. For example, if the person's behavior in a situation is very atypical, we could discount it as an exception and not let it influence our overall image of the person much."
Researchers say that these biases in human cognition could be a problem if you have to interview with someone you already know or get legal advice from a friend.
It's also a problem in the classroom, where that first impression on the teacher sticks with you the entire school year. For example, a professor who considers his student to be highly intelligent will probably tend to overestimate that student's performance in an oral exam,
The second study was a survey by the UK Bingo Site Paddy Power Bingo. It found that four in 10 women would rather spend time with their girlfriends than their husband. The survey also found that a third of the women surveyed felt it was easier to talk about serious issues with other women, rather than men.
