Intelligence is not enough

"The general notion that intelligence (analysis, logic, and argument) is enough is dangerous in many ways. The emphasis is on the logical rather than perceptual skills, which are so important in real-life thinking and doing. The ability of an intelligent person to avoid obvious errors and to put together a coherent argument often blinds that person to the need to develop deliberate thinking skills. The avoidance of error is certainly not enough in thinking."
