<i>but it&#x27;s also ok to formulate testable hypotheses in here.</i><p>That&#x27;s a bit odd... you&#x27;re basically advocating &quot;[formulating] testable hypotheses&quot; simply to post-justify a choice you&#x27;ve already made.<p>That&#x27;s basically science backwards...<p>It&#x27;s also human nature.  We all love to rationalize.  But we can at least see it for what it is. :)<p>Edit:<p>Incidentally, I have personally witnessed the fact that buying a bike has absolutely no correlation with frequency of riding it... ;)
