Joe Rogan Experience #2547 - Daniel Everett · Aired Aug 27, 2026
Claim summary · not a verbatim quotation
NASA conducted a study determining that a minimum of 500 people is required to successfully colonize another planet.
The finding
What the evidence shows
There's no NASA study behind this number. The actual academic research on minimum population for a multi-generation space voyage comes from anthropologist John Moore, who put the number at around 80 to 160 people, and later work by Cameron Smith put a safer estimate in the tens of thousands. Neither of those is a NASA project, and neither lands on 500.
