The “So” Tell: When you see an argument on the Internet that begins with the word “So…” you can be sure that what follows is a mischaracterization of the other side’s point followed by sarcasm and derision over the mischaracterization (but not the actual point). The sarcasm and derision are good persuasion because they act as an emotional penalty for maintaining the opinion that is under fire. But generally the “so…” structure of an argument causes both parties to debate the characterization versus debating the actual point.

Appeal to Experts: As long as there is at least one expert on the other side of a topic, the experts as a whole are not persuasive. To be clear, if you are introducing yourself to an unfamiliar topic, the number of experts on each side might matter. But for familiar topics such as climate change, it only matters that some experts are on the other side. And there are always experts on the other side of controversial topics.

What if the situation were reversed? Lately it has become common to address any criticism about your team by speculating that the situation would be viewed differently if the other team were being accused of the same misdeeds. While this might be true in some cases, it is an intellectual point in the same way as hypocrisy, and thus it has minimal persuasive power. The only power it might have is embarrassing the media toward a more even-handed approach in the future. But it won’t change anyone’s opinion about the current topic.

Hypocrisy: Pundits like to point out that politicians often criticize others for the very things they have done. That sort of observation is good entertainment but it is an intellectual exercise with no emotional power. You need emotion to persuade. And hypocrisy is such a universal human quality that it’s hard to get worked up about it when you see it.
