TBH I have my doubts about how effective "facts" are at actually changing peoples minds and influencing behavior (as opposed to just being something people share on Facebook to validate their preconceived notions)
People are predictable. If you can manipulate facts then you can control output. Hence the societal importace of getting real fact-givers again.
The whole "we feel justified lying about the benefits of X and Y because it gets a desired result" only works if you can keep it a secret. Which they won't be able to regarding 2020.
