Foraging for Alternatives: Ecological Rationality in Keeping Options Viable
Do we invest irrational amounts of effort into keeping options viable, or do we manage available and threatened options in an adaptive fashion? To ask and answer this question, we advocate an approach that considers the dynamic properties of decision environments. By linking the exploration-vs.-exploitation dilemma to animal foraging, we show that preserving and abandoning options can both be a...
متن کاملKeeping Doors Open: The Effect of Unavailability on Incentives to Keep Options Viable
M of the options available to decision makers, such as college majors and romantic partners, can become unavailable if sufficient effort is not invested in them (taking classes, sending flowers). The question asked in this work is whether a threat of disappearance changes the way people value such options. In four experiments using “door games,” we demonstrate that options that threaten to disa...
متن کاملWhen to Walk Away: The Effect of Variability on Keeping Options Viable
In this work we explore a variant of a classic explore/exploit dilemma based on a recent study by Shin and Ariely (2004).

Contrary to expectations, the mere presence of additional options did not substantially incre...

متن کاملKeeping kinetochores on track.
The multiple functions of kinetochores are reflected in their complex composition, with over a hundred different proteins, which self-associate in several functional subcomplexes. Most of these kinetochore proteins were identified over the last 10-12 years using a combination of genetic, cell biological, biochemical, and bioinformatic approaches in various model organisms. The key challenge sin...
