Yes, I believe uncontrolled emotions can interfere with intelligence, or at least the expression of intelligence. Emotions are important but it is possible to be blinded by these emotions. At the same time emotions can complement intelligence. It can be challenging, but we are at our best when we are able to distinguish between the two and keep them in balance.
I'm gonna keep this short.
Look at lisicki in the Wimbledon final this year. Tennis is a struggle of emotions but if you think and use your mind to control emotions you can succeed. Once Lisicki emotions got into her head she lost the game. Another example is lust. Many people make poor decisions and rape occurs, pregnancy occurs because people are following the lustful decisions of 'their penises' rather than thinking!
