As Dave Barry pointed out, when he was a kid, menus looked like this:<br /><br />Beef $3.95<br />Fish $2.95<br />Spaghetti $1.95Steve Sailerhttps://www.blogger.com/profile/11920109042402850214noreply@blogger.comtag:blogger.com,1999:blog-19346366.post-60954523590254079392009-12-06T17:30:09.926-05:002009-12-06T17:30:09.926-05:00That's different.

Marginal ideas can be used even when there's only one product, strategy, etc. The standard example is diminishing marginal utility -- that applies even if there are no alternatives to the product. You get less satisfaction from each further mouthful of ice cream even if that's all there is to eat.<br /><br />In frequency dependent selection, there are at least two ways to go, but the genetic success of either depends on how frequent it is. Standard example is playing the defecting strategy in prisoner's dilemma games.<br /><br />When cooperators are very common, a rare defector gets paid handsomely and the frequency of the relevant genes start spreading. However, if defectors are very common, the next defector will get hurt, pushing down the frequency of defecting genes.<br /><br />So going with a mostly-image strategy vs. a mostly-narrative strategy is a form of frequency dependent selection. When one of those strategies is rare, it's easy to profit from it; when it's very common, it's tough to profit from it.agnostichttps://www.blogger.com/profile/12967177967469961883noreply@blogger.comtag:blogger.com,1999:blog-19346366.post-57900666347138062252009-12-06T00:31:52.379-05:002009-12-06T00:31:52.379-05:00It's called marginalism.It's called <a href="http://en.wikipedia.org/wiki/Marginalism" rel="nofollow">marginalism.</a>Anonymousnoreply@blogger.com
