Bill Kanasky, Jr., Ph.D. talks about the biggest mistake witnesses make during testimony: guessing. Bill describes why this happens, even in light of clear direction to not guess, and how to address it. Bill talks about the attention/behavior gap which is driven by the brain's native neurocognitive wiring and explains the two categories of reasons why witnesses guess: internal and external reasons.

External factor: Plaintiff counsel.

Lastly, Bill covers the four things your witnesses cannot say during testimony: 1. "I think..."; 2. "I believe..."; 3. "I assume..."; 4. "I probably....".
