I think this study fails to give serious thought to the phonetic differences of the left-side and right-side letters, and the possibilities for co-correlation there.
The right side has 4 out of 6 of the vowels and 3 out of 4 of the other sonorants, which could easily be argued to be the more sonorous or pleasing sounds in a word. 7 out of the 11 right-hand letters fall into one of those categories.
By contrast, the left side is only 3/15 sonorants. Further, the left side has all the sibilants and a strong majority of the stops.
Pointing out that right-side letters correlate with agreeability is an interesting finding. Claiming that which side of the keyboard the letters are on is the _causal_ factor for agreeability strikes me as lazy.
