Dark Tactic:

1. An unwitting research company could be contracted to do a survey by an unethical organization.
2. The survey could use the trick where by asking some question that people will mostly say "yes" to and then ask a similar question later where the wording is slightly changed to agree with the viewpoint of the unethical organization.
3. Most people end up saying they agree with the viewpoint of the unethical organization.
4. The reputation of the research company is abused as the unethical organization claims they "proved" that most people agree with their point of view.
5. A marketing campaign is devised around the false evidence that most people agree with them.

They already trick people in less expensive ways, though. I was taught in school that they'll do things like ask 5 doctors whether they recommend something and then saying "4 of 5 doctors" recommend this to imply 4 of every 5 doctors when their sample was way too small.
