Thus, Socrates is mortal. The conclusion follows from the first two statements. Anti-lock brakes reduce the likelihood of skidding. Thus, installing such brakes will reduce the number of accidents. Many intersection accidents involve cars colliding at right angles.
Traffic lights reduce the frequency of right-angle collisions.
Thus, installing lights will reduce the number of intersection accidents. Because of the apparent similarity with the Socrates case, it may be tempting to assume that the conclusions in the two arguments are valid. The similarity, however, is deceptive and the conclusions are wrong. And people are more likely to agree with an erroneous conclusion when this fits their social attitudes and preconceptions. To err is human, but human, also, is awareness of that very fact.
