Stereotype Threat
The term refers to being at risk [given a specific set of contextual circumstances] of confirming a negative stereotype about one's social group as a self-characteristic [i.e., a personal trait]. For example, Let's say that you find yourself in a situation in which you realize that someone may have a steretotype about you [because of you physical appearance, gender or any other general characteristic of social group] and there is a part of you that is afraid that your [about to be undertaking] action and behavior will prove to that person that the stereotype is true. The concept was first introduced in seminal publication of Steele and Arsonson (1995) (see also ResearchGate link).
