- In [[Generalists are selected when evaluated by sum]], I wrote that if you want to adopt a specialist, you should not select him or her by summing the scores of several judges.
- [[Niche Top Strategy for Cross-fertilization]] wrote about how multiple specialties can create value through cross-fertilization.
  • The former is a phenomenon that in two dimensional standard normal distribution, Mr. B is chosen over Mr. A, who is the sharpest in the total score.

  • The latter is not the case.

    • Especially when the axis is widely known, many people will apply optimization in the direction of that axis
    • Then people will be distributed thickly around the axis.
    • The mixing area becomes a blank space.

    • Under these circumstances.
      • A, with his keen ability, is of course valuable.
      • Talk about comparing B and C.
        • Mr. C with average ability on X-axis
        • Mr. B, who is inferior to Mr. C on the x-axis but has moderate ability on the y-axis
        • In a comparison of the two, Mr. B tends to win in business terms.
        • While Mr. B can promote the value of “bridging the X and Y axes”, Mr. C cannot.
        • Mr. C tries to appeal his ability on the X axis, but that’s average, so he can’t use it as a point of appeal.
  • The statistically natural hypothesis is the former figure, where the X and Y axes are independently normally distributed, but observing reality, the latter is more plausible.
