It is possible that the incest taboo arose this way, I suppose, and certainly it seems likely that it is intertwined with the Westermark effect in some way, but they are still not the same thing. They sometimes apply to different people: e.g., the Westermark effect will not apply to siblings raised apart, but the incest taboo still does; the Westermark effect, but not the incest taboo, applies to unrelated kibbutzim raised together.

Also, my impression is that the Westermark effect does not make the relevant relations seem disgusting so much as just uninteresting, whereas violations of incest taboo typically do evoke reactions of disgust (from third parties - presumably at least one of a pair violating the incest taboo will actually be enjoying it).
