Passage Summary: An official points out that violations went down after fines went up, so they conclude that raising fines even more will make violations go down even further.

Conclusion: The city should raise parking fines again to further reduce the number of parking violations.

Reasoning: A previous increase in parking fines six months ago coincided with a 50 percent drop in parking violations.

Analysis: The official is falling for a classic correlation-versus-causation trap. While the fines went up, a new parking garage also opened at the exact same time; the garage might be the real reason violations dropped. Furthermore, the argument assumes that if a little bit of a 'cure' works, a lot more of it will work even better, which ignores the possibility of diminishing returns. Look for an answer that points out the failure to consider alternative causes for the drop in violations.
