Honesty “nudge” fails to replicate

Adaptation to desiccation fails to generate pre- and postmating isolation in replicate Drosophila melanogaster laboratory populations.

Many laboratory speciation experiments have raised allopatric populations in different environments to determine whether reproductive isolation evolves as a byproduct of adaptation (a form of ecological speciation). Few, however, have addressed the evolution of both pre- and postmating isolation or investigated the conditions affecting the process. We present results of an evolution experiment ...

Who Is Easier to Nudge?

We study heterogeneity in the responsiveness to choice architecture, focusing on the propensity of low-income versus high-income employees to opt out of the default contribution rate in 401(k) retirement savings plans. We develop a statistical model to distinguish between two underlying sources of heterogeneity: low-income employees may be more likely to remain at the default because it is simi...

To nudge or not to nudge: cancer screening programmes and the limits of libertarian paternalism.

'Nudging--and the underlying idea 'libertarian paternalism'--to an increasing degree influences policy thinking in the healthcare sector. This article discusses the influence exerted upon a woman's choice of participation in the Danish breast screening programme in light of 'libertarian paternalism'. The basic tenet of 'libertarian paternalism' is outlined and the relationship between 'libertar...

How to Securely Replicate

We present a method for constructing replicated services that retain their availability and integrity despite several servers and clients being corrupted by an intruder, in addition to others failing benignly. We also address the Issue of maintaining a causal order among client requests. We illustrate a security breach resulting from an intruder’s ability to effect a violation of causahty in th...
