Main findings

Even a penny helps' (lpd/'low bar') increases contribution incidence (appears strongly replicated) but sometimes reduces conditional contribution ('scale-back'); net effect varies. Mediated by anchors and expectations


Practical relevance

May be easier to legitimate small donations in effective (humanitarian) contexts because of low living costs… Seems a common practice in international giving (“for the price of just a cup of coffee”)
