0.30 to 0.40

Explanation:

In the research study titled "Behavior as a function of the situation", in 1983, David Funder and Daniel Ozer, examined the results of three classic social psychological studies. They converted the results to effect sizes and found that the effects were equivalent to correlations in the range of 0.30 - 0.40.

According to them, the linear effects of incentive for counterattitudinal advocacy on attitude change, of degree of "hurry" and number of onlookers on bystander intervention, and of proximity of authority and "victim" on obedience average slightly less than 0.40.
