I am honestly surprised anything like this can pass the ethic committee. The reputational risk seems huge.

For example, in economics departments there is usually a ban on lying to experiment participants. Many of them even explicitly explain to participants that this is a difference between economics and psychology experiments. The reason is that studying preferences is very important to economists, and if participants don’t believe that the experiment conditions are reliable, it will screw the research.
