That&#x27;s an appealing and intuitive idea to me too, yeah; but they have validated that it&#x27;s actually the case on a large population of users.  Their paper seems very methodologically careful&#x2F;thorough.  It&#x27;s also interesting to me that they correlated this with the post-game player-feedback.<p>Its easy to say &#x27;we knew that&#x27; post hoc, but they&#x27;ve done the science.  (Also, hindsight bias is a real thing.)<p>This seems like the opening step in a line of research.
Its like in Feynman&#x27;s &#x27;cargo cult science&#x27; address about the (apocryphal?) experimenter &#x27;Young&#x27;: this is learning how to carefully do science in this domain.  <a href="http:&#x2F;&#x2F;calteches.library.caltech.edu&#x2F;51&#x2F;2&#x2F;CargoCult.htm" rel="nofollow">http:&#x2F;&#x2F;calteches.library.caltech.edu&#x2F;51&#x2F;2&#x2F;CargoCult.htm</a>
