Harold,
 
Thanks for posting this.  These are 3 points that my husband and I frequently discuss as they relate to a variety of issues.  I will definitely share these with him.

For a reflective time: I just ran across three principal biases identified in
1974 and recounted by Jerome Groopman in 2009 in the context of medical
diagnosis. They seem relevant to genealogical diagnosis as well!

    "anchoring," where a person overvalues the first data he encounters and so is
skewed in his thinking;

    "availability," where recent or dramatic cases quickly come to mind and color
judgment about the situation at hand; and

    "attribution," where stereotypes can prejudice thinking so conclusions arise
not from data but from such preconceptions.

[end quote]

New York Review of Books 56(17):26, 5 November 2009, citing Amos Tversky and
Daniel Kahneman, "Judgment Under Uncertainty: Heuristics and Biases: Bias in
Judgments Reveals Some Heuristics of Thinking Under Uncertainty," Science
I185(4157), 1974.
