My research is primarily in the area of judgment and decision-making, and my work is informed by evolutionary theory (especially principles of complementary levels of explanation; see here). Specific topics of interest cross multiple applied and basic science disciplines, with a focus on the common thread of understanding the psychology of risk.
My research program comprises three primary lines. First, I examine the role of individual differences in explaining patterns of risk-taking, including gambling. Second, I examine how situational conditions of need motivate decisions under risk. Third, I examine how inequality and resultant socioemotional comparison mechanisms affect decision-making processes and outcomes in numerous domains. A brief research statement that broadly summarizes my research program can be found here.

*** All PDFs are for personal use only and not for commercial use or redistribution. Academic publishers reap disturbingly high profits from a free labor model — research and peer review — that is funded largely by governmental agencies (and thus, taxpayer money). Still, we apparently have to be cautious about disseminating taxpayer funded work publically to the taxpayers who deserve unfettered access to it.
*** Supporting data for all papers published prior to 2018 cannot be shared. The consent forms approved by the relevant human ethics boards indicated to participants that their data would only be shared among named researchers, and that data would be destroyed within 5-7 years of collection. I recognize in hindsight these procedures were a serious mistake given the new realities of open science. However, participants cannot consent retroactively to changed terms. All ethics protocols for data collected in 2018 and afterwards include provisions for public data sharing (and all data will accordingly be made public here).
