A balanced approach that considers human strengths and weaknesses will lead to a more flattering set of empirical findings, but will distract researchers from focusing on the mental processes that produce such findings and will diminish the practical implications of their work. Psychologists ought to be doing research that is theoretically informative and practically relevant, exactly as they are doing.

Gilead et al. present a rich account of abstraction. Though the account describes several elements which influence mental representation, it is worth also delineating how feelings, such as fluency and emotion, influence mental simulation. Additionally, though past experience can sometimes make simulations more accurate and worthwhile, many systematic prediction errors persist despite substantial experience.
