Gould was a paleontologist, not a geneticist. Gould's reputation is zero in evolutionary biology, an industrious fool.
See this letter to the editor if you want to see what the giants of evolutionary biology thought of Gould:
John Maynard Smith, one of the world's leading evolutionary biologists, recently summarized in the NYRB the sharply conflicting assessments of Stephen Jay Gould: "Because of the excellence of his essays, he has come to be seen by non-biologists as the preeminent evolutionary theorist. In contrast, the evolutionary biologists with whom I have discussed his work tend to see him as a man whose ideas are so confused as to be hardly worth bothering with, but as one who should not be publicly criticized because he is at least on our side against the creationists." (NYRB, Nov. 30th 1995, p. 46). No one can take any pleasure in the evident pain Gould is experiencing now that his actual standing within the community of professional evolutionary biologists is finally becoming more widely known. If what was a stake was solely one man's self-regard, common decency would preclude comment.
But as Maynard Smith points out, more is at stake. Gould "is giving non-biologists a largely false picture of the state of evolutionary theory" -- or as Ernst Mayr says of Gould and his small group of allies -- they "quite conspicuously misrepresent the views of [biology's] leading spokesmen."[1] Indeed, although Gould characterizes his critics as "anonymous" and "a tiny coterie," nearly every major evolutionary biologist of our era has weighed in in a vain attempt to correct the tangle of confusions that the higher profile Gould has inundated the intellectual world with.[2] The point is not that Gould is the object of some criticism -- so properly are we all -- it is that his reputation as a credible and balanced authority about evolutionary biology is non-existent among those who are in a professional position to know: http://cogweb.ucla.edu/Debate/CEP_Gould.html

They really, truly have not been debunked. If you are willing to read a short book on the topic, I would recommend this one which has an epub version here: https://archive.org/details/IntelligenceAllThatMatters/page/...
If you are interested in the truth, I ask you to approach this subject bloodlessly, as you would a programming problem. Read the book I linked to. Then re-read Measure of Man, if you must.
But before you do, allow yourself to consider that bio-determinism is allowed to be true. There is no god or law of physics that prevents this from being the case. Imagine that these were just brute facts. If they were, your actions may change but your normative commitments do not have to.
I think if you read the literature neutrally, you will find g-factor is basically coherent and well-motivated, and intelligence is heritable. But when reading on matters touched by ideology, I think it is important to allow yourself to believe you can be persuaded.
