Facilitating Scientific Communication Between Strangers: A Preregistered Lost E-Mail Experiment

Communication scholars are increasingly concerned about biases that shape people's interactions with science. Past study has focused on echo chambers (cultivating social networks that reinforce existing worldviews). People's facilitation of scientific discourse between strangers also may be shaped by their attitudes. To study the latter, we employed a recent adaptation of Milgram's lost letter technique called the lost e-mail technique (LET). We conducted a preregistered field study using a large undergraduate university sample (N = 1,508) to examine how the LET might elucidate people's treatment of scientific information. We distributed four ostensibly misaddressed scientific messages and monitored the likelihood of these e-mails being facilitated by participants. Participants' beliefs about self-esteem's importance, assessed months earlier, were associated with increased facilitation of scientific claims congruent with (vs. incongruent with) these beliefs. Thus, people shape the spread of online information in a manner matching their beliefs, even for people outside their social networks.

Automated summary

This article discusses the increasing concern among communication scholars about biases in people's interactions with science. It suggests that attitudes play a role in shaping people's facilitation of scientific discourse even between strangers. Through a field study using the lost e-mail technique, the researchers examine how people's beliefs are associated with their facilitation of scientific claims.
