Learned behaviour gives way to natural style and tendancies:

• withdraw to think about the central issue that needs attention
• suggests various ideas and use feedback received to support the intellectual analysis
• debate the issue from an intellectual point of view and leave it very late before making a decision
• criticise others efforts and ignore their feelings

Extreme stress may cause the INTP shadow type to appear - a negative form of ESFJ:

• expressing intense negative emotions towards others
• being very sensitive to criticism
• becoming preoccupied with details, without any logical basis
• interpreting facts or events in a very subjective way
