When Hindsight Is 20/20

When every $P$-flat ideal is flat

In this paper‎, ‎we study the class of rings in which every $P$-flat‎ ‎ideal is flat and which will be called $PFF$-rings‎. ‎In particular‎, ‎Von Neumann regular rings‎, ‎hereditary rings‎, ‎semi-hereditary ring‎, ‎PID and arithmetical rings are examples of $PFF$-rings‎. ‎In the context domain‎, ‎this notion coincide with‎ ‎Pr"{u}fer domain‎. ‎We provide necessary and sufficient conditions for‎...

POND-Hindsight: Applying Hindsight Optimization to POMDPs

We present the POND-Hindsight entry in the POMDP track of the 2011 IPPC. Similar to successful past entrants (such as FF-Replan and FF-Hindsight) in the MDP tracks of the IPPC, we sample action observations (similar to how FFReplan samples action outcomes) and guide the construction of policy trajectories with a conformant (as opposed to classical) planning heuristic. We employ a number of tech...

Hindsight biased policy evaluation ∗

In this paper we present a political-agency model in which voters exhibit a cognitive deficiency known as hindsight bias: after the uncertainty about an event is resolved, they consider the realized outcome more foreseeable than it actually was. For their reelection decision, voters evaluate the politician’s ability based on the history of observed actions and outcomes. High ability is defined ...

Hindsight bias among psychiatrists.

It is crucial to minimize bias when offering forensic opinions; however, to our knowledge there are few, if any, existing data examining whether psychiatrists are susceptible to one source of such bias, hindsight bias. In the current study, 235 general and forensic psychiatrists reviewed hypothetical cases in which patients with suicidal or homicidal ideation presented for psychiatric care. We ...
