 Once confounding factors across the three types of tasks are controlled for, Jarvstad et al.’s results suggest that (i) the perception-cognition gap is largely explained by differences in how performance is assessed; (ii) the decisions by experience vs decisions by description gap (Hertwig, Barron et al. 2004) is due to assuming that exogenous objective probabilities and subjective probabilities match; (iii) people’s ability to make high-level decisions is better than the biases and heuristics literature suggests  (section 7.1);  and (iv) differences between subjects are more important for predicting performance than differences between the choice tasks (Jarvstad et al. 2013).
