Thanks for posting,

I'm afraid I don't quite follow your rationale for eliminating
(D) at first glance. You say:
yiwoo0216 Wrote:The stimulus essentially states that IRRESPONSIBLE analysts are targeted thereby preventing them from making exaggerated claims ... which would normally allow me to cross off answer D at first glance.
Can you explain a bit further? It sounds a bit like you believe that
(D) contradicts the premise that a
future board would deter irresponsible analysts from making exaggerated claims. But
(D) does not contradict this.
(D) is saying that
right now, without an existing board, the only analysts who claim handwriting analysis is reliable are themselves irresponsible. That does not undermine the premise.
If
(D) is true, and right now there are no responsible analysts who claim handwriting analysis is reliable, then this board of Gregory's may well find itself with no licensed analysts who could actually testify in court that handwriting analysis was reliable. If that were true, it's hard to conclude handwriting analysis is going to be "a legitimate courtroom tool" - no one could use it! So,
(D) opens up a potential weakness for Gregory's conclusion!
Now,
(D) does not definitively prove Gregory's proposed board won't work. Perhaps, as you and
Mike.kim both acknowledge, the board will give licenses to irresponsible analysts who outwardly pretend to be responsible, and who can ALSO claim without exaggerating that handwriting analysis is reliable. But that's okay! Weakeners do not have to prove the argument wrong, just damage it a bit, and make the conclusion a bit less likely to follow.
In this situation, if all the analysts are irresponsible, that would at the very least make the board's job more difficult! It opens up some distinct possibilities that would make it less likely we'd end up with handwriting analysis as a legit courtroom tool.
Does that help clear things up a bit?
AD HOMINEMLet's also address the issue of
ad hominem. A classic example of this would be to say that Bob's argument must be wrong because Bob smells. The critical aspect that makes this an
ad hominem is that the criticism has no bearing on the argument itself.
If the attack were instead, say, that Bob's claim is suspect because Bob is known to be a liar, that would not be an
ad hominem. It's still an attack on Bob's character, but it's one that has some direct bearing on the reliability of his claim.
Another version of
ad hominem might be that Bob's argument is invalid because his sister smells. Again, the attack is not relevant to the substance of the argument (presumably).
In this situation, you worry that criticizing the board because the analysts are irresponsible follows this last pattern. But there are a few key differences. If the character attack on the analysts makes a logical difference in assessing the board, then it is a reasonable point. If all the analysts were pathological liars, for instance, then that fact would have real bearing on whether the board was capable of getting its job done and allowing handwriting analysis to be a legit courtroom tool. In other words, that attack would not be an irrelevant consideration at all.
The responsibility of the analysts is not raised as an unconnected character attack. Rather, it is raised to undermine the reliability of handwriting analysis for the courtroom as a general matter!
Please don't hesitate to follow up with additional questions if there's anything that is still at all unclear!
