Subject: Ad Hominum Arguments are not Persuasive

Go up one level in this thread


Graham,

You go too far.  Time to back off.

Let me serve you a little of your own dish.  You are sure to like it.  :)

You can say anything you want about the programmers of chess programs.  You can
try to demean their character or psychoanalyze them all you want.  You might
even make a point or two that hits close to home because you are a good amateur
psychologist or a good study of people.

Well, la dee da!  (this means I ridicule the approach--not you the person, but
the approach you have chosen).  However, I am very sorry that you the person
chose this approach.  It is wrong and silly at the same time.

The 'ad hominum' (sp?) argument (attack the human) fails to rebut the logic and
evidence supporting their arguments regarding how strong current programs are,
at tournament time controls (40/2), on a human FIDE rating scale.

Trying to establish bias (or non-objectivity) on the part of programmers does
not mean that *your* contra opinion about strength of programs is true.  It does
not take the real evidence they have drawn upon to support their cases and show
with your own logic how that evidence actually supports your case instead of
theirs.  Adducing evidence about the programmers opinions does not produce one
whit of evidence that your counter-opinion is more accurate, more logical, or
more supported by evidence laid bare for the world to see and judge.

Programmers point to actual games and actual game results against strong
competition (examples--Rebel challenge matches, spoken of by Ed Schroder in
below posting; Hyatt pointing to his trials of Crafty versus strong players).
They draw well reasoned and logical conclusions from those actual test results.

You cannot make programs appear stronger by attacking their programmers'
personalities and demeaning their objectiveness.  In fact, this method of
advancing your own opinion only serves to weaken your own case.  By grasping at
weak straw after weak straw, attempting to thereby build a solid framework for
your opinion, you reveal the true weakness of your own evidence.  It shows you
have no stronger, more solid support to rely on and share with interested
readers.  Who in their right mind would produce weak arguments when they had
better arguments in hand?

Apparently this is of no concern to you.  Consequently you seem to stretch to
find any way at all, using even the most demeaning of methods (ad hominum
attacks), to support your position.

Analogy--You cannot make a borderline great horse a great horse in the eyes of
the judging public (if indeed you are trying to be persuasive) by complaining
that the jockey or trainer's opinion of the horse is too modest or too biased.
The horse doesn't run any worse or better because you toy with the human
connections psyche.  The horse's ability is evidenced bottom line by actual
runnings, actual trials, against great competition, and analysis thereof.  This
is evidence, not all the rubbish about the connections.  (better watch myself,
starting to sound Hyatt-like!  :) )

As another example of your grasping at straws, I posted far below about your
argument drawing upon Selective Search ratings and statements to bolster your
opinion about program strength.  I indicated several seemingly serious flaws to
that approach of yours--due to lack of evidence about the Selective Search
figures, how calculated and based on what.  I pointed out that Selective Search
admitted there was a likely difference between comp-comp and human-comp ratings,
yet the Selective Search rating is admittedly based on a combination of both
types of play--without ever publishing the basis for their ratings.  And you
relied on those ratings without applying a critical eye of your own to test the
evidence you hoped you were providing.

Once again, you didn't rise to the occasion to logically defend your own use of
a second-hand (at best) conclusion, undocumented, non-interpretable and devoid
of supporting evidence.  Instead you avoided discussion of my points on the
merit (lack, actually) of your approach.  In fact, you never directly replied to
my post.  You didn't acknowledge the merit of my concerns about your approach
nor try to mitigate them by evidence or your own logic.  Who is avoiding
competition (here, logical argument), you or a programmer?

To me this means you intentionally avoided addressing serious concerns about the
flaws in your arguments--another sign you don't care seriously to defend your
espoused opinion with strong backup and will often say anything, no matter how
devoid of substance it is.

You indicated, however, in reply to a replier to my post that you would try to
locate that Selective Service published evidence I asked for, in your back
issues of Selective Search.  I have not yet seen the actual evidence to back up
*your* arguments, *your* logic (lack of it, in my opinion).  It may be there, I
don't say it isn't (although I strongly believe it isn't there), but you have
not produced it, nor admitted in the interim that you do not actually have it.

Now here, for the umpteenth time, you are posting about the strength of computer
programs, this time drawing on your finely honed skills of psychobabble.  Nice
job!  really supports your opinion doesn't it?  not to mention your character!

What gives, my friend?  Are you unable to carry on civil discourse with wit,
logic and aplomb?  Do you have any evidence you wish to discuss in our CCC
forum?  If so, bring it to the table, please.  Publish it here.  We all enjoy
discussing such stuff.

But please don't stoop to attacks on the programmers in the hopes that it makes
your own arguments look better.  It really is demeaning of you, in my opinion.

However, it is a free (although moderated) forum.  Say what you want until you
get messages deleted or are banned.

If you produce good evidence and good logic, I will happily concur with the
merits of your points.  If you chose to ignore real evidence and attack
personalities, I will speak up.  Your reputation will suffer by continuing.  Why
do it?

P.S. I am not always right.  Feel free to reply.  But please address my concerns
about your methods and your choices to support your opinions.  This is what I am
opposing.  Not your right to have an opinion and express it, with or without
logic or evidence to support it. Just your obstinate means of trying to support
it in any manner, no matter how personally derisive and insulting it may be to
others.
