Misses the point of the statement you quote.

Please explain.

Alicorn could (and likely did) believe that Eliezer is better equipped to or has simply had more motivation to look into things like probability of success

I can't exclude that that was her reasoning, but cryonics requires a significant lifelong financial committment, and conditional on the belief that it might actually work with non-negligible probability, the choice of the organization and type of service becomes paramount (for instance, IIUC, CI's typical service results in even much more ischemia than Alcor's). Why would you make such an important decision just by copying what somebody else did, in particular when this person is not an expert?

On the other hand, if you want to signal allegiance and gain status within a community, it makes perfectly sense to emulate the alpha.
