Matching on provider is risky

Banking on a bad bet. Probability matching in risky choice is linked to expectation generation.

Probability matching is the tendency to match choice probabilities to outcome probabilities in a binary prediction task. This tendency is a long-standing puzzle in the study of decision making under risk and uncertainty, because always predicting the more probable outcome across a series of trials (maximizing) would yield greater predictive accuracy and payoffs. In three experiments, we tied th...

Development Approach Is Risky

System (EOSDIS). Because the Committee intends to undertake extensive oversight of EOSDIS, you asked that we examine several key aspects of NASA'S system development approach, including the extent to which EOSDIS (1) will use prototyping to reduce system development costs and risks, and (2) may require technologies that are beyond the current state of the art. The report identifies weaknesses i...

Is ICSI Risky?

As assisted reproductive technology (ART) methods become the mainstream of infertility treatment, it has become even more critical to reassess its safety. Following the results of a study published by the Robinson Institute in the New England Journal of Medicine, the risk of ART, especially intracytoplasmic sperm injection (ICSI), has never been so closely scrutinized. This paper traces the ori...

Is alarm calling risky? Marmots avoid calling from risky places.

Alarm calling is common in many species. A prevalent assumption is that calling puts the vocalizing individual at increased risk of predation. If calling is indeed costly, we need special explanations for its evolution and maintenance. In some, but not all species, callers vocalize away from safety and thus may be exposed to an increased risk of predation. However, for species that emit bouts w...
