Your example is too narrow. Change "eat more ice cream" to "try and cool off" and you'll have a more accurate analogy. And yes, a heat wave drives almost all people to try and cool off.Again, a general foundation in a broad subject of risk v reward cartot v stick does not domehow turn into proven fact that a specific carrot and stick has impact on changing behavior of a concrete discrete and extrene result.
People on the whole tend to eat more ice cream when its hot as a truth - does not mean a heat wave drives almost all people to extremes of ice cream gorging.
Just like removal of death tax does not drive almost all players to video game resave play that they did not do before.
