Thiel's stagnation thesis held that technological progress has slowed since the 1970s.

This is a claim about what Thiel's previously published stagnation thesis said. True: his earlier writings and talks state that technological progress slowed beginning in or around the 1970s. Examples are 'The End of the Future' (National Review, 2011), Zero to One, the 'We wanted flying cars, instead we got 140 characters' Founders Fund manifesto, and his debates and lectures. Mostly true: his thesis dated the slowdown slightly differently (for example the late 1960s or 1973), or limited it mainly to the world of atoms while exempting computing and the internet, but still described a general slowdown of progress from roughly that era. Mixed: his earlier statements conflict about the timing or scope. Mostly false: the thesis as published placed the start well away from the 1970s or did not claim a general slowdown. False: Thiel never advanced such a thesis.

   “the easy, the sort of macroeconomic manifestation of this is the relative stagnation in wages in the U.S. since the early 1970s”

The claim is about what Thiel's stagnation thesis said, so his earlier published statements are the record being checked. In a 2014 RealClearMarkets interview (E2), Thiel said that "since the 1970s we've been in an era of relative technological stagnation," but he exempted computers, the internet and the mobile internet. The criteria rate that limited scope as mostly true. A 2014 transcript (E4) adds that he pointed to wage stagnation in the U.S. since the early 1970s as a sign of the slowdown. E1 is dated after the judging date, so it was not used.
