I think this is a huge oversimplification. Just as intelligence can be either effective or ineffective or even destructive, so can love or emotionalism. We can do things in the name of love or compassion that are actually harmful.

A classic example would be cultural traditionalism trying to hold onto some kind of authenticity but really just creating tyranny and repression, or attempts to rein in the worst parts of capitalism that backfire and impoverish people.

Meanwhile the coldest reason can deliver a lot of compassion. The Haber process for cracking atmospheric nitrogen probably saved more lives than all the saints in history.
