Adolescents do not always act in ways that serve their best interests, even as defined by them. Contextually, perceptions of risks by the youths tend to be lower, thus increased underestimation of the risks associated with the behaviors. Through this, many adolescents tend to engage in risky actions and behaviors because of their perception of invulnerability. However, some of these adolescents tend to take risky actions because they fell vulnerable to the point of approaching hopelessness. In both cases, the variation in perceptions results in adolescents making poor and risky decisions that leave them vulnerable to physical and psychological harm.
