Experiments on Human Behaviour

Read 2 interesting experiments on human behaviour. First one:

Researchers led by the psychologist Dacher Keltner took groups of three ordinary volunteers and randomly put one of them in charge. Each trio had a half-hour to work through a boring social survey. Then a researcher came in and left a plateful of precisely five cookies. Care to guess which volunteer typically grabbed an extra cookie? The volunteer who had randomly been assigned the power role was also more likely to eat it with his mouth open, spew crumbs on partners and get cookie detritus on his face and on the table. – “Cookies Monster Experiment”, on how power changes a person’s behaviour.

And this:

We asked people to put on blindfolds and then to pick up a red jellybean from one of two plates that held a mixture of red and white jellybeans. We offered $1 to anyone who could pick up a red bean. Here’s the catch: While one plate held 20 jellybeans and the other 100, the plate with 20 beans had a higher percentage of red ones. We put up signs that told people this clearly: “10 percent red” of the small plate and just “7 percent red” of the big plate. Surprisingly, even with the percentage signs in front of them, a third of the people picked the plate with 100 beans. – How people think about probability, influence by visual cue? Source: here.
