Convergent thinking is a type of thinking that uses logic to find in a short time the best solution to a problem. This is the opposite of divergent thinking that uses creativity and non-linear thought to find multiple alternative solutions to solve a problem. This implies if you use convergent thinking you are not creative but simply use logic to address a problem.
For example, in a test, you should use convergent thinking because there is only one correct solution to each question and you need to get to this in a short time. According to this, it is false convergent thinking utilizes creativity to generate possible solutions because the type of thinking that does this is divergent thinking.
