The author assumes that “sufficient profits” must be the “highest profits.” But perhaps oil profits are sufficient to motivate risky investments, even though they’re not the highest among all industries.

The politician never attacks the character of oil companies, nor does she attack the substance of their conduct. She just argues that regulations don’t need to be tightened because oil companies’ profits aren’t high enough.

This is the cookie-cutter flaw of confusing correlation for causation. The politician doesn’t make this mistake. Instead of a causal assumption, she makes a conditional assumption that is not supported in her argument.

The politician does provide evidence in the form of “recent data” to support her claim that the oil industry does not have the highest profits among all industries.

This is the cookie-cutter flaw of hasty generalization. The politician doesn’t make this mistake. She draws a specific conclusion about oil industry regulations based on evidence that is also about the oil industry.
