‘No Simple Explanations’

It's no accident: Our bias for intentional explanations.

Three studies tested the idea that our analyses of human behavior are guided by an "intentionality bias," an implicit bias where all actions are judged to be intentional by default. In Study 1 participants read a series of sentences describing actions that can be done either on purpose or by accident (e.g., "He set the house on fire") and had to decide which interpretation best characterized th...

Explaining Legislative Leadership Delegation : Simple Collective Action or Conditional Explanations ?

Explanations Count Explanations Count

In research areas such as decision support systems, one of the crucial features is the ability to automatically explain decisions. However, this ability does not typically play a large role in computer games. Here, I suggest that this situation will change: research on the automatic generation of explanations will have real import for many types of computer games. I discuss four possible ways t...

No Arbitrage Conditions For Simple Trading Strategies

Strict local martingales may admit arbitrage opportunities with respect to the class of simple trading strategies. (Since there is no possibility of using doubling strategies in this framework, the losses are not assumed to be bounded from below.) We show that for a class of non-negative strict local martingales, the strong Markov property implies the no arbitrage property with respect to the c...

No Tranfer of Training in Simple Addition

Several researchers have proposed that skilled adults may solve single-digit addition problems (e.g. 3+1=4, 4+3=7) using a fast counting procedure. Practicing a procedure often leads to transfer of learning and faster performance of unpracticed items. Such transfer has been demonstrated using a counting-based alphabet arithmetic task (e.g., B+4 = C D E F) that indicated robust RT gains when unt...
