This is, not to put too fine a point on it, crank science. Opening up the linked document, the DOI fails to resolve, the paper investigates pH variations in urine during tide cycles, and also skimming over it doesn't appear to make a single prediction. This is at best unfalsifiable, and a "break with the scientific community" is an accurate assessment.
The physics of tides is largely well-understood, and the moon and sun provide the primary forcing. Accurate tide tables are regularly computed the world over, with measurements regularly made. Without even looking at measurements, the shipping industry demands accurate tide forecasts for navigating efficiently. The claim that "tidal phenomena are... primarily electromagnetic" requires some serious evidence to back it up, with calculates to boot, rather than invoking mysticism that tides are "beyond us". Many things are beyond our current scientific understanding, and that is humbling, but tides are quite well understood.
An intervention on the household someone is raised in is not the same as an intervention on race. This is part of what it means when people say racism is a structural problem: people are, systematically, treated differently in many different parts of their lives. The USA is a country where, within living memory, the insurrection act was invoked to allow black children to attend a school which wanted to segregate them.
Leaving aside the question of what IQ actually measures, the authors of the single study you cite interpret the results as inconclusive due to confounding factors. The mainstream position in biology is that race is not a biological concept [1]. It seems that you are trying to argue that there is some immutable difference between races, a position usually described as scientific racism. As you are not aware of evidence-based arguments against scientific racism, there are studies showing a reduction of the "Racial IQ Gap" [2], as well as papers reviewing scientific racism in the literature [3] where it is argued that much contemporary research promoting ideas of immutable racial differences fail to meet evidentiary and ethical standards.
