Summer is better than winter because summer sports are more enjoyable than winter sports; plus, it's warm and sunny outside.

Which logical fallacy is shown?

• Fallacy of the single cause

• Cherry picking

• Reversing causal direction

• Slippery slope

Answer explanation

It relies upon choosing only the data or evidence (that summer sports are more fun and that it's sunny and warm) that will lead to a desired outcome (convincing someone that summer is better than winter) rather than revealing the full picture (there are things about the summer that many dislike—increased mosquito population, humidity, greater likelihood of sunburn, and so forth).

There is no way that my cousin values the environment if he chooses to work for a company responsible for a large oil spill.

Which logical fallacy is shown?

• Genetic fallacy

• Post hoc fallacy or false cause

• Cherry picking

• Slippery slope

It assumes that A) the cousin is the same as B) a company responsible for a large oil spill. Simply because the cousin works for a company that acted irresponsibly in regards to the environment does not mean that he does not care for the environment.

My boyfriend always attends my cheerleading competitions. He failed to attend the last competition and we lost. If we are to continue winning competitions, my boyfriend must be in the audience.

Which logical fallacy is shown?

• Slippery slope

• Post hoc fallacy or false cause

• Reversing causal direction

• Genetic fallacy

Answer explanation

It implies that because the person's boyfriend did not attend the cheerleading competition, her team lost. Whether or not her boyfriend is in the audience, there are many factors that contribute to the winning or losing of such a competition. It is highly unlikely that there is any causal relationship between his failure to show up and the team's loss.
