Three

find
that
people
disproportionately
choose
spouses,
places
to
live
and
occupations
with
names
similar to their own. Analyzing the same and additional data I
find that the existing evidence is spurious.

rebuttal to this paper. Here is

Defense of Diligence".

February V48(1) p.1-12 (.pdf)
Consumer Reports released & then
retracted info on carseat safety. Surprisingly, people successfully
ignored the retracted information.

(2008) "When Rational Sellers Face Non-Rational Consumers: Evidence
from Herding on eBay," Management

eBay bidders choose auctions with more
bids, so sellers start them cheap.
