Psychologist David Elkind defined what he called adolescent egocentrism, including components of the personal fable, i. e. the idea that you are the center of everyone’s attention; and the myth of invincibility, i. e. the idea that nothing can harm you. A teenager refusing medical care demonstrates which of these concepts?

The myth of invincibility

Explanatifon:

"The myth of invincibility" was identified by David Elkind, who argues that it is a strong component of the personal fables that adolescents tend to construct.

These fables are part of their adolescent egocentric view, which often makes them engage in activities that put them at risk without evaluating the consequences for health or their life

Driving at high speed, or drug abuse are typical examples where adolescents feel that nothing will happen to them.

they are unable to be aware by themselves of the danger they put themselves in.
