> Logically, this sum cannot exceed 100 percent. The chance of the sum being exactly 100% is pretty low considering that they are subjective opinions on what percentage one thinks she or he is personally responsible for certain activity, and the spouses are separated from each other. As humans, we have cognitive biases and we don't access memories the way a server does. Simply inferring that "people often overestimate their importance in this world" from the experimental data that the couples’ estimates often added up to a number a lot bigger than 100% is an oversimplification of the matter. But since this is general psychology it is fine to have things this way perhaps.
