The journal article cited for this indicates not that smart people are happier with smart friends, but that &quot;More intelligent individuals actually experienced <i>higher</i> life satisfaction with <i>lower</i> frequency of contact with friends.&quot; <a href="http:&#x2F;&#x2F;www.ncbi.nlm.nih.gov&#x2F;pubmed&#x2F;26847844" rel="nofollow">http:&#x2F;&#x2F;www.ncbi.nlm.nih.gov&#x2F;pubmed&#x2F;26847844</a><p>A lot of the meta-articles seem to be hypothesizing that intelligence could be an evolutionary adaptation for dealing with novel circumstances, and intelligent people are therefore driven to attack these challenges -- thus making them unhappy when they are distracted.<p>This meshes with my experience -- while I certainly enjoy my highly intelligent friends, I have not developed time-consuming relationships with them, because we are often focused on our own particular highly specific challenges.
