The _____ is the overestimation of the degree to which everybody else thinks or acts the way we do.

A) fundamental attribution error
B) self-serving bias
C) stereotype threat
D) false consensus effect

The false consensus effect is the tendency to overestimate the degree to which other people share our beliefs or behaviors. This can be seen as a form of projection, where we assume that others are like us without considering individual differences or alternative viewpoints. The other options are not as closely related to this phenomenon. The fundamental attribution error is the tendency to overemphasize dispositional factors (such as personality traits) rather than situational factors when explaining behavior. The self-serving bias is the tendency to attribute successes to internal factors and failures to external factors. Stereotype threat refers to the negative impact that stereotypes and discrimination can have on individuals' performance and well-being.
