Gatekeeping: a Partial History of Cold Fusion

TL;DR

This paper examines the history of cold fusion as a case study of scientific gatekeeping, highlighting its initial rejection and recent resurgence despite controversy.

Contribution

It provides an opinionated overview of cold fusion's history, illustrating how scientific gatekeeping can influence the acceptance and persistence of controversial research.

Findings

Cold fusion was initially discredited by the scientific community.

Despite rejection, cold fusion research persisted and experienced a modest revival.

Recent funding indicates a shift in scientific gatekeeping attitudes.

Abstract

One of the most public episodes of gatekeeping in modern science was the case of so-called 'cold fusion'. At a news conference in 1989 the electrochemists Martin Fleischmann and Stanley Pons announced that they had found evidence of nuclear fusion in palladium electrodes loaded with deuterium. There was worldwide interest. Many groups sought to reproduce the results, most unsuccessfully. Within months, the prevailing view became strongly negative. The claims of Fleischmann and Pons came to be regarded as disreputable, as well as false. As the Caltech physicist David Goldstein put it, cold fusion became 'a pariah field, cast out by the scientific establishment' (Goldstein 1994). The case would already be interesting for students of gatekeeping if the story had ended at that point. Even more interestingly, however, the field survived and persisted. It has been enjoying a modest renaissance, with recent government funding both in the US and the EU. This piece offers an opinionated introduction to cold fusion as a case study of scientific gatekeeping, discussing both its early and recent history
