Public opinion poll was administered to 50 people before the election of president barack obama. polls taken before election night showed 50% of the people polled believed barack obama would be elected president. after the election results, the same people were asked if they believed barack obama would be elected president, and this time 75% of the people said yes. this may be an example of bias. a) transientb) hindsightc) egocentricd) stereotypical

correct option is b) hindsight

Explanation:

given data

before = 50 %

after = 75 %

we can also say here it is overestimation of one is capability to foresee outcome

and we have given that after result outcome of the election more number of  people agree that they also predict correct

so here we can say that correct option is b) hindsight
