Understanding the argument -
Historian: One traditional childrearing practice in the nineteenth century was to make a child who misbehaved sit alone outside. - Background info.
Anyone passing by would conclude that the child had misbehaved. - Background info.
Nowadays, many child psychologists would disapprove of this practice because they believe that such practices damage the child’s self-esteem and that damage to children’s self-esteem makes them less confident as adults. - opinion of many child psychologists. Traditional practice --> damages children's self-esteem --> less confident adults.
However, no one disagrees that adults raised under that traditional practice were, on average, as confident as adults not so raised. - Counterpremise.
Which one of the following can be properly inferred from the historian’s statements?
(A) The beliefs of many present-day child psychologists about the consequences of loss of self-esteem are incorrect. - The beliefs are incorrect and are hyperbolic.
(B) Some of the most confident adults, as well as some of the least confident adults, were raised under the traditional practice in question. - The argument just talks about the average. Maybe the most confident were raised under XXX practice, and maybe the least confident were raised under altogether different ZZZ practice. We have no information on what practices were used for these extreme scenarios. Distortion as it plays with the "average" word.
(C) With the traditional childrearing practice, passersby did not always make correct inferences about children’s behavior by observing them outdoors. - out of scope.
(D) The most confident adults are those who developed the highest level of self-esteem in childhood. - we don't know. What we know is that many child psychologists believe that the traditional practice --> damages children's self-esteem --> less confident adults. The "Might be true" category, is wrong, as we can't verify with 100% confidence from the argument.
(E) If children’s loss of self-esteem makes them less confident as adults, then the traditional childrearing practice in question did not tend to cause significant loss of self-esteem. - Yes. Basically, it means the traditional practice is not the cause.
