Like post hoc, slippery slope can be a tricky fallacy to identify, since sometimes a chain of events really can be predicted to follow from a certain action.

Whether or not this is truly an example of the straw man fallacy, I found it refreshing to see a student applying logical reasoning learned in another of his courses to the problem at hand.

Third, even if we ignore these two problems, there is the grave fallacy in the very concept of "social cost," or of cost as applied to more than one person.

Sometimes you cannot tell a scam is a scam until you see it up close, and then the sunk-cost fallacy will sometimes force you to make a poor choice.

Indeed, despite their errors, this attitude bodes well for the future, and is a heartening sign of a focus on human prosperity.
