In cryonics circles, it is not unusual to hear tales of a spouse - usually a wife, as most people presently signed up for cryopreservation at clinical death are male - who is adamantly opposed to cryonics, even to the point of requiring the potential cryonics patient make a choice between cryonics or the partner. This has always struck me as odd, but it is clearly more than just an urban myth or a few anecdotal couples; there is some core incentive or common aspect of human psychology at work here that generates these conflicts often enough to make the situation well known. (Well known to cryonics supporters, at least).
Robin, a deep thinker most at home in thought experiments, says he believes that there is some small chance his brain will be resurrected, that its time in cryopreservation will be merely a brief pause in the course of his life. Peggy finds the quest an act of cosmic selfishness. And within a particular American subculture, the pair are practically a cliche.
Among cryonicists, Peggy's reaction might be referred to as an instance of the "hostile-wife phenomenon," as discussed in a 2008 paper by Aschwin de Wolf, Chana de Wolf and Mike Federowicz. "From its inception in 1964," they write, "cryonics has been known to frequently produce intense hostility from spouses who are not cryonicists." The opposition of romantic partners, Aschwin told me last year, is something that "everyone" involved in cryonics knows about but that he and Chana, his wife, find difficult to understand. To someone who believes that low-temperature preservation offers a legitimate chance at extending life, obstructionism can seem as willfully cruel as withholding medical treatment. Even if you don’t want to join your husband in storage, ask believers, what is to be lost by respecting a man’s wishes with regard to the treatment of his own remains? Would-be cryonicists forced to give it all up, the de Wolfs and Federowicz write, "face certain death."
The article goes on to speculate as to just what may be the roots of this spousal opposition, and you'll find even more suggestions in the comments at Overcoming Bias.
For my part, I'd say it seems unreasonable (to say the least) to expect your partner to commit suicide to make you feel better - and abstaining from cryopreservation on death is exactly a form of suicide. The practice of suttee, in which widows were compelled to die upon their late husband's funeral pyre, is now generally acknowledged as barbaric and murderous. But at the high level it is little different from brow-beating a partner into abandoning cryonics, or worse, actively working to ensure that a partner's cryonics arrangements go awry. Still, a great many people for a long period of years accepted suttee as good and proper - just as a great many people today accept all sorts of correctable malignancies in cultures and the human condition.
What is accepted is no guide to what is right.
