Effective leaders can hold two opposing ideas in his head and still function optimally while rationalizing them creating an even better idea than the sum of earlier two.
Conventional thinkers:
1. Determining Salience. Focus only on obviously relevant features.
2. Analyzing Causality. Consider one-way, linear relationships between variables, in which more of A produces more of B.
3. Envisioning the Decision Architecture. Break problems into pieces and work on them separately or sequentially.

4. Achieving Resolution. Make either-or choices; settle for best available options.
Integrative/Effective thinkers:
1. Determining Salience. Seek less obvious but potential relevant factors.
2. Analyzing Causality. Consider multi-directional and non-linear relationships among variables.
3. Envisioning the Decision Architecture. See problems as a whole, examining how the parts fit together and how decisions affect one another.
4. Achieving Resolution. Creatively resolve tensions among opposing ideas; generate innovative outcomes.
i do agree with the above after observing my own thinking process and others.. and is it born or bred? i believe IQ is mostly born but the process of effective thinking is bred.
And if you understand the power and workings of the unconscious mind, it will be even better!!
