Rabbi Gordimer claims that there is no such thing as Modern Orthodox pesak, and that decisions by Modern Orthodox poskim “should look no different than if [they] were adjudicated by a chareidi posek; process (research) and product (conclusion) should be indistinguishable.” This is simply false, as anyone who knows the writings of Modern Orthodox poskim can attest. A posek is not a computer. All sorts of meta-halakhic considerations go into his rulings and this explains why a Modern Orthodox posek will come to different conclusions than haredi poskim on many issues. I am not referring to whether a tea bag can be used on Shabbat, as in this sort of case there shouldn’t be any differences between haredi and Modern Orthodox poskim, but in matters concerning which the two camps differ (e.g., the role of women) there will obviously be differences among the poskim.
For Rabbi Gordimer, all poskim share the same “process”. Not only is this historically incorrect, it isn’t even “doctrine”. Does he really think that there are any haredim who believe that Modern Orthodox poskim operate the same way as haredi poskim? Of course they don’t, which is precisely the reason why they reject Modern Orthodox halakhists, because they know that their meta-halakhic values influence their halakhic decisions. The haredim don’t oppose meta-halakhic values per se. Meta-halakhah has a very prominent place in haredi halakhah. It is the particular Modern Orthodox meta-halakhic values that they see as problematic.
