Neurosurgeons Put Cryonics Success at 72% vs 25.5% Across 334 Physicians

A PLOS One survey of 334 physicians found neurosurgeons gave whole-brain preservation and revival a 72% median chance of preserving critical psychological information, far above the 25.5% median across all respondents.
Only 27.9% of physicians overall said cryonic preservation leading to some form of revival was plausible or very plausible, while 47% judged the idea unlikely.
On end-of-life practice, 70.7% said anticoagulants such as heparin should probably or definitely be allowed to aid preservation, with just 11.7% opposed.
Legal support was weaker for starting preservation before death: 44.3% said it should probably or definitely be legal, while 28.8% opposed.
The authors, all active in cryonics-related organizations, argued the relatively low overall success estimate suggests the results were not simply skewed by pro-cryonics bias.

Why are brain surgeons three times more likely than other doctors to believe in revival from cryopreservation?

With doctors ready for pre-death cryo-prep, are our laws on defining death now obsolete?
