William Lane Craig diagnosed.

Dr. Craig suffers from the Dunning–Kruger effect:

This cognitive bias is when a, "relatively unskilled persons suffer illusory superiority, mistakenly assessing their ability to be much higher than it really is."

The bias was first experimentally observed by David Dunning and Justin Kruger of Cornell University in 1999. They postulated that the effect is the result of internal illusion in the unskilled, and external misperception in the skilled: "The miscalibration of the incompetent stems from an error about the self, whereas the miscalibration of the highly competent stems from an error about others."[1]

Dunning and Kruger proposed that, for a given skill, incompetent people will:[4]

• fail to recognize their own lack of skill
  
• fail to recognize the extent of their inadequacy
  
• fail to accurately gauge skill in others
  
• recognize and acknowledge their own lack of skill only after they are exposed to training for that skill
