During summer hiatus I have promised to look into a data set I have extracted
from one particular Facebook contest.
While many Facebook contests are not based on any logical reasoning, this
contest appeals to me as it appears to require at least some thought or
expertise. As far as I am aware, in Lithuanian schools, sets of linear equations
are typical 8th grader problem. Even this low threshold allows to reasonably
expect to observe herding behavior in the answers, because the ones who lack
expertise will simply copy what the others have publicly written.
This contest is particularly interesting to me, because either intentionally or
unintentionally there are infinitely many correct answers. It is so as the problem
in the contest involves less equations (two) than unknowns (three). Hence there
are no reasonable arguments for why to prefer one answer over the others.
