Two interesting papers.
- How Focusing on Individual-Level Solutions Has Led Behavioral Public Policy Astray (Chater & Loewenstein, 2022) “An influential line of thinking in behavioral science, to which the two authors have long subscribed, is that many of society’s most pressing problems can be addressed cheaply and effectively at the level of the individual, without modifying the system in which individuals operate. Along with, we suspect, many colleagues in both academic and policy communities, we now believe this was a mistake. Results from such interventions have been disappointingly modest. But more importantly, they have guided many (though by no means all) behavioral scientists to frame policy problems in individual, not systemic, terms…”
- No evidence for nudging after adjusting for publication bias (Maier, et al., 2022) ‘Thaler and Sunstein’s “nudge” (1) has spawned a revolution in behavioral science research. Despite its popularity, the “nudge approach” has been criticized for having a “limited evidence base” (e.g., ref. 2). Mertens et al. (3) seek to address that limitation with a timely and comprehensive metaanalysis. Mertens et al.’s headline finding is that “choice architecture [nudging] is an effective and widely applicable behavior change tool” (p. 8). We propose their finding of “moderate publication bias” (p. 1) is the real headline; when this publication bias is appropriately corrected for, no evidence for the effectiveness of nudges remains…’
