The article assumes that people make such decisions rational, which is just not the case. If you ask someone 'which argument or fact could possibly convince you to sign up, or lets say at least treat the cryo option favorably' you do not get a well reasoned argument about chances of it working or personal preferences or so, but more counterarguments. Throwing more logic at the problem does not help! If you find a magic argument that suddenly convinces someone that is not convinced yet - or does the signing process more immediate than planned, then you probably learned something useful about human nature that can be applied in other areas as well.
