In graphology, thinking has to do with HOW the person thinks, not what he thinks about or how much quality there is to his thinking.
“HOW” breaks down into four categories:
(1) Cumulative or methodical thinker – the person who is inclined to consciously process “new” ideas or challenges through a thought process.
(2) Comprehensive thinker – the person who is prone to allow his automatic reactions – based on memories of past experiences – to determine his thoughts in the moments.
(3) Analytical thinker – the person who feels that it is necessary to analyze every-thing about a given situation (whether he is familiar with it or not) before he is comfortable enough to take action.
(4) Investigative thinker – the person with an inquisitive mind and the desire to explore for himself whatever interests him. He will not be satisfied with second-hand information.
