Empirical research in positive psychology indicates that positive illusions and cognitive biases can offer significant psychological benefits, such as enhancing resilience, improving subjective well-being, and aiding recovery from adversity.

Papers [3] and [4] explicitly demonstrate these positive psychological functions. None of the provided papers refute the claim.
