Let he who is without cognitive bias cast the first lecture.

47. Neither of you did, in my opinion.

Here, again, is the article:

Cognitive Bias
A cognitive bias is a mistake in reasoning, evaluating, remembering, or other cognitive process, often occurring as a result of holding onto one's preferences and beliefs regardless of contrary information. Psychologists study cognitive biases as they relate to memory, reasoning, and decision-making. Many kinds of cognitive biases exist. For example, a confirmation bias is the tendency to seek only information that matches what one already believes. Memory biases influence what and how easily one remembers. For example, people are more likely to recall events they find humorous and better remember information they produce themselves. People are also more likely to regard as accurate memories associated with significant events or emotions (such as the memory of what one was doing when a catastrophe occurred).
