DESCRIPTION:Ronald van den Berg will cover:\n\nPerceptuo-motor\, cognitive
 \, and description-based decision-making seem equally good\;\nA. Jarvstada
 \, U. Hahna\, S. K. Rushtona\, and P. A. Warrend\, PNAS (2013)\n\nhttp://w
 ww.pnas.org/content/110/40/16271.short\n\nClassical studies suggest that h
 igh-level cognitive decisions (e.g.\, choosing between financial options) 
 are suboptimal. In contrast\, low-level decisions (e.g.\, choosing where t
 o put your feet on a rocky ridge) appear near-optimal: the perception–co
 gnition gap. Moreover\, in classical tasks\, people appear to put too much
  weight on unlikely events. In contrast\, when people can learn through ex
 perience\, they appear to put too little weight on unlikely events: the de
 scription–experience gap. We eliminated confounding factors and\, contra
 ry to what is commonly believed\, found results suggesting that (i) the pe
 rception–cognition gap is illusory and due to differences in the way per
 formance is assessed\; (ii) the description–experience gap arises from t
 he assumption that objective probabilities match subjective ones\; (iii) p
 eople’s ability to make decisions is better than the classical literatur
 e suggests\; and (iv) differences between decision-makers are more importa
 nt for predicting peoples’ choices than differences between choice tasks
