@pschwede I made no assumption either way, you wouldnt need to in fact. brown bonbons are a category of bonbons which happen to include chcocolate bonbons. The two ideas have overlap, they dont need to be identical.

Its similar to how statistics about humans have relevance when talking about women or jews or any category.

The result would be that the correlations would be weaker than a more precise set of data (specific to chocolate). But even with weaker correlations we can still make predications, those predictions are just likewise weaker.

The point is, my assumptions here actually wouldnt hurt in making the prediction itself. The nature of statistics is kinda brilliant this way. If we assume two things are strongly related, and they turn out not to be, the statistics will reflect this for us, even if we may not know why.
