than would be the case if their incomes more nearly represented their
real worth. Payment according to the product, with prizes and bonuses so
much opposed by the unions, is more in accord with the principles of
eugenics.

PROHIBITION

It was shown in Chapter II that the attempt to ban alcoholic beverages
on the ground of direct dysgenic effect is based on dubious evidence.
But the prohibition of the use of liquors, at least those containing
more than 5% alcohol, can be defended on indirect eugenic grounds, as
well as on the familiar grounds of pathology and economics which are
commonly cited.

1. Unless it is present to such a degree as to constitute a neurotic
taint, the desire to be stimulated is not of itself necessarily a bad
thing. This will be particularly clear if the distribution of the
responsiveness to alcoholic stimulus is recalled. Some really valuable
strains, marked by this susceptibility, may be eliminated through the
death of some individuals from debauchery and the penalization of others
in preferential mating; this would be avoided if narcotics were not
available.

2. In selection for eugenic improvement, it is desirable not to have to
select for too many traits at once. If alcoholism could, through
prohibition, be eliminated from consideration, it would just so far
simplify the problem of eugenics.

3. Drunkenness interferes with the effectiveness of means for family
limitation, so that if his alcoholism is not extreme, the drunkard's
family is sometimes larger than it would otherwise be.

On the other hand, prohibition is dysgenic and intemperance is eugenic
in their effect on the species in so far as alcoholism is correlated
with other undesirable characters and brings about the elimination of
undesirable strains. But its action is not sufficiently discriminating
nor decisive; and if the strains have many serious defects, they can
probably be dealt with better in some other, more direct way.

We conclude, then, that, on the whole, prohibition is desirable for
eugenic as well as for other reasons.

PEDAGOGICAL CELIBACY

Whether women are more efficient teachers than men, and whether single
women are more efficient teachers than married women, are disputed
questions which it is not proposed here to consider. Accepting the
present fact, that most of the school teachers in the United States are
unmarried women, it is proper to examine the eugenic consequences of
this condition.
