Argument 33

A new study collected data that shows that people who snore are more likely to gain weight

than are people who do not snore. It is well known that many people who snore also stop

breathing frequently during the night for a few seconds, a condition called sleep apnea. The

interruption of breathing wakes the person---often so briefly that the waking goes

unnoticed---and can leave the person too tired during the day to exercise. Anyone who snores,

therefore, should try to eat less than the average person and to exercise more

In this argument the speaker concludes that any person who snores should try to eat less

and exercise more than the average person. To justify this conclusion the speaker points out

that many snorers awaken frequently during sleep--often so briefly that they are unaware that

they are awake in order to catch their breath (a condition called sleep apnea), and as a result

are too fired during normal waking hours to exercise. The speaker also cites data collected

during a recent study, suggesting that snorers are more likely to gain weight than other people.

This argument is flawed in several critical respects.

First, the speaker provides no assurances that the recently collected data suggesting a

correlation between snoring and weight gain are

statistically reliable. Perhaps the study's

subjects were unrepresentative of the overall population in terms of other traits and habits

that might affect body weight. Lacking such evidence the speaker simply cannot draw any firm

conclusions based on the study about the relationship between snoring and weight gain.

Even assuming a strong correlation between snoring and weight gain among the general

population, the speaker has not adequately shown that sleep apnea causes weight gain. A

correlation is one indication of a causal relationship, but in itself does not suffice to prove such

a relationship. It is entirely possible that some other medical condition, or some other trait or

habit, that causes snoring also causes weight gain. Without establishing dearly that snoring at

least contributes to weight gain, the speaker cannot convince me that snorers should either eat

less or exercise more than the average person.

Even ifmany snorers suffer from sleep apnea and tend to gain weight as a result, the

speaker's advice that "anyone who snores" should try to eat less and to exercise is new

ertheless unwarranted. It is entirely possible that some--or perhaps even most--snorers do not

suffer from sleep apnea, or are not too tired to exercise, or do not in any event tend to gain

weight. Without ruling out these possibilities, the speaker must expressly limit the advice to
