Wait a second:
Arkes & Ayton cite 2 studies finding that committing sunk cost bias increases with age - as in, children do not commit it.
Information is worth most to those who have the least: as we previously saw, the young commit sunk cost more than the old
These are in direct contradiction with each other. What gives?
They are in contradiction, but the latter claim is supported by the large second paragraph in the children (the section that 'previously saw' was linking to) where I quote the criticism of the 2 studies and then list 5 studies which find either that children do commit it on questions or that avoidance increases over lifetimes, which to me seem to override the 2 studies.
I just finished the first draft of my essay, "Are Sunk Costs Fallacies?"; there is still material I need to go through, but the bulk of the material is now there. The formatting is too gnarly to post here, so I ask everyone's forgiveness in clicking through.
To summarize:
(If any of that seems unlikely or absurd to you, click through. I've worked very hard to provide multiple citations where possible, and fulltext for practically everything.)
I started this a while ago; but Luke/SIAI paid for much of the work, and that motivation plus academic library access made this essay more comprehensive than it would have been and finished months in advance.
