Attacking Faulty Reasoning T. Edward Damer, Third Edition p. 131:
I can't help but think that you are the cause of this problem; we never had any problem with the furnace until you moved into the apartment." The manager of the apartment house, on no stated grounds other than the temporal priority of the new tenant's occupancy, has assumed that the tenant's presence has some causal relationship to the furnace's becoming faulty.
(日本語訳)「私はあなたが問題の原因だと思わずにはいられない。あなたがこのアパートに引っ越してくるまで暖房設備には何の問題もなかった」このアパートの大家は、新しい入居者が入居してから問題が起きたという前後関係のみを根拠として、暖房設備が故障したことと因果関係があると仮定した。

With Good ReasonS. Morris Engel, Fifth Edition p. 165):

More and more young people are attending high schools and colleges today than ever before. Yet there is more juvenile delinquency and more alienation among the young. This makes it clear that these young people are being corrupted by their education.
