Recently thinking about effective sibling relationships wrt startups, e.g. @kimbal/@elonmusk & @patrickc/@collision. A natural, fully-trustworthy partner who’s easy to sync with = massive force multiplier, w/ compounding effects from childhood on?

Huh. That’s bizarre. Any theories?
-
Not sure. Coordination is overrated? Being different in a collaboration is in fact extremely important? One twin is, despite genetics/upbringing, still too likely to be a 'weakest link' and hold the other back/be jettisoned? Twinship itself destroys creativity/risk-taking?
-
I've previously wondered if (unconsciously) people only seek to excel if they have cues telling them that there is an empty high place they stand a good chance of doing best in, thereby gaining status in exchange for their risks. Maybe a twin never feels best enough.
-
If so, would that be caused by genes, or environment, or a combination? Or something else?
-
EY's theory sounds like a clear-cut environmental effect. No?
-
My theory was environmental. Part of my trying to understand what seems to me like a “conservation of agency” phenomenon.
-
If it’s true, though, we might expect some cases of accomplishment in identical twins raised apart. A slight change on the usual test that always shows that environment apparently has no influence on people.
-
Yes. Offhand, I don't recall my impressions of MZA studies indicating anyone of great accomplishment. MZA samples are so tiny, though, and often lower-class, that it's very minimal evidence against the theory.

The Winklevii don't do it for you?
-
Certainly not. Can you name 3 more examples? You probably can't, though identical twins are 0.5% of the population, there are tens of thousands of famous or successful people you could name, so there should be easily >25 such pairs if they had no net advantages at all.
-
The Bee Gees?
-
Jose and Ozzie Canseco were both MLB pro, though clearly Jose was markedly more successful. Hmm wonder who took better steroids
-
Rex and Rob Ryan both coached in the NFL, surely that counts. There, three pairs.
-
I've never heard of any of those NFL/MLB people, and if you're going to go as far back as the Bee Gees, over half a century ago, the set of famous/successful people becomes way larger than just 'tens of thousands' and now there should be hundreds or thousands of identical twins.
-
The fact that you haven't heard of Jose Canseco tells me something about your interests, but is irrelevant to his fame, which is considerable. The same is true of the Bee Gees. This isn't Blue Oyster Cult. Top 100 successful bands of the 20th century by revenue, easy.
-
The point is you're selectively drawing from an ever-expanding elastic pool. How many tens or hundreds of thousands of people are there with WP or other articles if we include anyone back to the 1950s? The harder you have to search, the more you emphasize how few there are.

Oh wait, do you have a handy link for the claim in the parenthesis?
-
Not particularly. There was some Florida study I vaguely recall where the penalty was like -2 IQ points. It comes up in the twin study literature because environmentalists are always going 'maybe identical twins are *totally different* from regular people!' They're only a little.
-
It could have been more challenging for twins in other times.
-
Twins have been compared to non-twins going back a century now to like the 1920s if not earlier.
