DYOR is an attitude, if not quite a practice, that has been adopted by some athletes, musicians, pundits and even politicians to build a sort of outsider credibility. “Do your own research” is an idea central to Joe Rogan’s interview podcast, the most listened to program on Spotify, where external claims of expertise are synonymous with admissions of malice. In its current usage, DYOR is often an appeal to join in, rendered in the language of opting out.Nowhere are the contradictions of DYOR on such vivid display as in the world of crypto, where the phrase is a rallying cry, a disclaimer, a meme and a joke — an invitation to a community as well as a reminder of its harsh limits.
