Newcomb's Paradox has only one admissable subject<br>behavior: take just the one box.<br><br>An evolutionary proof of this is as follows: suppose that<br>box A either does or does not contain dinner, and box<br>B always contains dessert. One may live on a steady
<br>diet of box A, but one gradually dies of nutritional<br>deficiencies by selecting only box B.<br><br>(Those familiar with Newcomb's Paradox should skip<br>the present paragraph. The AI, or Deity, or whatever<br>entity has an unassailable track record of always
<br>seeming to know whether you will always take just<br>box A or whether you will succumb to the temptation<br>to take both boxes. In some accounts---like wikipedia's<br>---it is "box B" which contains the necessary (or extremely
<br>desireable) reward, but in other accounts that box is<br>called "A".)<br><br>Thus evolution would suggest that taking just one box<br>is an ESS. Or, as Jef Albright would say, taking only<br>the one box works.
<br><br>In my own essay, I provide reasons why we should<br>regard "changing the past" as eminently reasonable<br>from the point of view of the subject. (See<br><a href="http://www.leecorbin.com/UseOfNewcombsParadox.html">
http://www.leecorbin.com/UseOfNewcombsParadox.html</a>).<br><br>Note the analogy to the free will discussion that we have<br>been having. If you imagine an audience, especially one<br>composed of physicists (and--better yet--physicists who
<br>love you and want only the best for you), then as the<br>Alien made his assignment for the boxes two weeks<br>ago in their plain public view, the past will not be changed<br>by anything you do. Moreover, since the Alien is always
<br>correct, from the point of view of the audience you do<br>not have free will.<br><br>But from your point of view---which should be regarded<br>as on an equal footing with theirs, at least operationally,<br>you do!<br>
<br>For if you try on some days to take both dinner and dessert,<br>then you cannot avoide the unmistakeable feeling that you can<br>*control* whether or not the main box contains dinner. As<br>a functioning organism you must adopt this point of view
<br>that you *can* decide. Philosophical niceties such as "oh, well,<br>it's all determined what you will do" are not usefully<br>descriptive of your actions or your situation.<br><br>If you were part of a team who every night had to make
<br>a *decision* as to whether to take one or both boxes,<br>your patter about not having choice, or about the contents<br>of the boxes being already determined, would be received<br>with jeers and sneers by the others. You would quickly
<br>abandon the language-modality [1] of determinism, and adopt<br>the language-modality of free will.<br><br>Many people here are quick to disparage the concept of<br>free will as utter nonsense. But we compatibalists counter
<br>by emphasizing its utility in daily discourse, and are wont<br>to remind our critics of the primary role of language in<br>describing not only our world, but necessarily a world<br>in which we devices are embedded.<br>
<br>As in every night when you hold arguments with the fools<br>who want to take both boxes, you (and they) really are<br>agreeing that choice is possible.<br><br>Go ahead if you want and discard the notion of free will,<br>
but are you going to also discard the notion of a machine<br>(e.g. you) being able to make a decision? I have not<br>heard any of the anti-compatiblists answer this question.</blockquote><div><br>This is an interesting take on Newcomb's Paradox. The one-boxers will ultimately prevail, and therefore one-boxing will become the accepted way of life. But doesn't this just show that a belief in free will has been cultivated by the Alien's experiment while, at the same time, even the variability in choice you would expect from a wild population is being expunged? Truth is not a matter of utility.
