Logic is about clear, effective, and efficient thinking. It is a science and an art. It is not something that we either have or lack when we are born -- it is something that we must study and practice.
We all know intelligent people who do not always express themselves logically. The likelihood is that their ability to think logically has not been properly developed.
Logic (which in no way excludes emotional feelings, by the way) is certainly helpful in overcoming deception, both from without and within. Please read a well-written (and short!) introduction to the basics of logic, published by the "OWL at Purdue":
