A quick look at Wikipedia casts doubt on that. Wiki would love the corrections if you've got them. I checked mostly because I didn't think a dozen astronauts had walked on the moon-- then once I was there. . . .
Armstrong & Duke -Eagle Mitchell & Scott - Life
No mention of scouting- Aldrin, Conrad, Bean, Shepard, Irwin, Young, Cernan, Schmitt
I don't doubt that a lot of Eagle scouts have done well. There are a couple million of them, more or less, so it is likely that lots of them did well. [chances are that as a cross section of society, they counted among the more privileged class so we should expect them to do better than average]
But how do they rate against their peers? It would take a real effort to sort them out, take a sample and compare their futures-- but if we're just going to cite random scouts-- I've known 3 in my life.
1 was a good man, though outside of scouting you wouldn't call him remarkable.2 others were not. They didn't do as poorly as Eagle scouts Lee Harvey Oswald, or serial killer scouts Robinson & Whitman, - but they were general ne'er do wells.
