Harmful in what sense? Making people choose actions that are less adaptive
means making them choose actions that lead to fewer descendants. The paper
is about what actions better satisfy the preferences of the people involved,
whether that leads to more or fewer descendants.

As economists usually define social welfare, this would not improve social
welfare. Even if a few consumers gain, many more consumers would lose, as
would producers. All these gains and losses are from the point of view
of the preferences of the people involved.
