In a heated debate about the proximity of COVID-19 herd immunity, White House health advisor Dr Scott Atlas proclaimed 'You're supposed to believe the science, and I'm telling you the science' 1 . A group of infectious disease experts and former colleagues from Stanford, however, publicly criticized Dr Atlas, who is a radiologist, for spreading 'falsehoods and misrepresentation of science' through his statements about face masks, social distancing and the safety of community transmission 2 . In the 2020 pandemic crisis, all eyes turned to scientific experts to provide advice, guidelines and remedies; from COVID-19 alarmists to sceptics, appeal to scientific authority appeared a prevalent strategy on both sides of the political spectrum. Please see the Supplementary Information for a short commentary on how the current work might relate to the COVID-19 situation.A large body of research has shown that the credibility of a statement is heavily influenced by the perceived credibility of its source [3][4][5][6][7][8][9][10] . Children and adults are sensitive to the past track record of informants [11][12][13][14][15][16] , evidence of their benevolence toward the recipient of testimony [17][18][19] , as well as how credible the information is at face value 20,21 . From an evolutionary perspective, deference to credible authorities such as teachers, doctors and scientists is an adaptive strategy that enables effective cultural learning and knowledge transmission [22][23][24][25][26][27][28] . Indeed, if the source is considered a trusted expert, people are willing to believe claims from that source without fully understanding them. We dub this 'the Einstein effect'; people simply accept that E = mc 2 and that antibiotics can help cure pneumonia because credible authorities such as Einstein and their doctor say so, without actually understanding what these statements truly entail.Knowing that a statement originates from an epistemic authority may thus increase the likelihood of opaque messages being interpreted as meaningful and profound. According to Sperber 29 , in some cases, incomprehensible statements from credible sources may be appreciated not just in spite of, but by virtue of their incomprehensibility, as exemplified by the speech of spiritual or intellectual gurus (the 'Guru effect'). Here, we investigate to what extent different epistemic authorities affect the perceived value of nonsensical information. To this end, we contrasted judgements of gobbledegook spoken by a spiritual leader with gobbledegook spoken
