答案和详解如下：

Q1. Correct answer is B)

Blackwood developed her investment style through trial and error, learning from her own mistakes. This is a sign of heuristic-driven bias. The other statements could be true of many types of investors who are not bound by heuristic-driven bias.

Q2.Correct answer is B)

The process of developing heuristic-driven bias starts with developing investment principals through experience, followed by reliance on heuristics (rules of thumb) to make decisions. At this point, imperfect heuristics start to sway investment decisions, and investors make errors. Bad advice can contribute to all of these steps, but it is not a part of the development of heuristic-driven bias.

Q3. Correct answer is B)

Trial and error, and experimentation are heuristic learning processes. Heuristic learners pick up information simply, through their own efforts or from sources simple to access. They don't do research.

Q4. Correct answer is A)

Tom is overconfident. Tom believes that on the basis of his five-year record, he can continue to outperform a benchmark. His record could be due to luck and he may be not reporting his shortcomings as an investor.

Q5. Correct answer is B)

As an overconfident investor, Heggins will tend to underestimate risk. He will also tend to overestimate the impact of an event on stocks. By overestimating the impact of positive events, he will likely experience negative surprises in the future. The overestimation of the impact of negative events will lead to positive surprises in the future.
