Your second sentence is not logically implied by the first sentence.
It is not uncommon to have phenotypes that are expressed only rarely although the genes that code for the phenotype are widely dispersed. Many well known genetic diseases fall into this category.
- danieltillett 11y agoIntelligence is like height in that it is multi-genetic (on the order of thousands of genes). Any trait that is determined by thousands of genes is going to show a normal distribution.
- apalmer 11y agoI understand the reasoning behind that... however the whole point of this study was to put this logical assumption under the rigors of actual science... because this is an 'assumption' not a logical 'conclusion'.
- danieltillett 11y agoI just said I would have been surprised if the result was anything other than they found, not that the study was not worth doing. For something as important as intelligence it is worth checking all of our assumptions. This study does support what previous studies have found from when people looked for genes that had a large positive effect on intelligence and failed to find any.
