The optimum portfolio depends on the various expectations of choices available and the degree of variance in performance which is tolerable. The greater the number of selections, the less will be the average year-to-year variation in actual versus expected results. Also, the lower will be the expected results, assuming different choices have different expectations of performance.
Those who are most sensitive about "politically incorrect" terminology are not the average black ghetto-dweller, Asian immigrant, abused woman or disabled person, but a minority of activists, many of whom do not even belong to any "oppressed" group but come from privileged strata of society.

He is also better qualified than the average individual to protect himself in peril, for he is observant and resourceful.
The voyage of the best ship is a zigzag line of a hundred tacks. See the line from a sufficient distance and it straightens itself to the average tendency.
All large political doctrines are rich in difficult problems - problems that are quite above the average citizen's reach. And that is not strange, since they are also above the reach of the ablest minds in the country; after all the fuss and all the talk, not one of those doctrines has been conclusively proven to be the right one and the best.
If you invested in a very low cost index fund - where you don't put the money in at one time, but average in over 10 years -you'll do better than 90% of people who start investing at the same time.
Laws, religions, creeds, and systems of ethics, instead of making society better than its best unit, make it worse than its average unit, because they are never up to date.
If we teach only the findings and products of science - no matter how useful and even inspiring they may be - without communicating its critical method, how can the average person possibly distinguish science from pseudoscience?
