What? How?
Applying Eugenics under race science of course doesnt work, in the same way that applying the principles of combustion to a pencil will not enable you to write...
However, actually applying Eugenics in itself does not lead to "false conclusions". E.g. if person X has an inheritable disease, and then person X does not breed, then indeed his inheritable disease will not be passed down to offspring due to his not having bred.
What false conclusion can you draw from the lack of breeding not producing children?
