Interested in what influences & affects your brain and your behavior? Here are some of the most powerful psychological effects to look out for today:
1) Pratfall Effect- These mistakes attract charm as a result of the Pratfall Effect: Those who never make mistakes are perceived as less likeable than those who commit the occasional faux pas. Messing up draws people closer to you, makes you more human. Perfection creates distance and an unattractive air of invincibility. Those of us with flaws win out every time.
2) Pygmalion Effect- . At the beginning of the year, all the students took an assessment test, and the experimenter led other teachers to believe that certain students were capable of great academic achievement. Experimenter chose these students at random, regardless of the actual results of the IQ tests. At the end of the year, when the students were retested, the group of earmarked high achievers did indeed show improvement over their peers. Why? Later tests concluded that teachers subconsciously gave greater opportunities, attention, and feedback to the special group. Their expectations for this group were higher, and their expectations created the reality.
The applications for the Pygmalion Effect can have benefits for both personal development and leadership. Individually, you can challenge yourself with more difficult goals and tasks in an effort to rise to meet the challenge. As a leader, when you expect great things of your team, you may see improved performance in return.
3) Paradox of choice- Happiness is diminished with the extra effort and stress it takes to weigh multiple options, opportunity cost affects the way we value items, pressure to choose can be draining, and the possibility of blame exists should the decision not turn out how we had hoped.
4) Bystander effect/ “confusion of responsibility” -diffused responsibility: They assume someone else will pick up the slack.
5) Spotlight Effect-To test the Spotlight Effect, a team of psychologists at Cornell asked a group of test subjects to wear an embarrassing T-shirt (featuring a picture of Barry Manilow’s face) and estimate how many other people had noticed what they were wearing. The estimations of the test subjects were twice as high as the actual number.
6) Focusing Effect- people make decisions on the basis of the most pronounced and distinct information they have available in their working memory, and for this reason, other pieces of possibly useful information are excluded. So, the decision is only based on fractions of the total amount of knowledge or information that one has stored.
The easiest way to handle it is to start asking yourself questions. “What happened last time I did that?” “Is it reasonable to assume that that single action caused that outcome?” “If not, what else might have contributed to that outcome?” “How many other factors were in play?”
