Lay people don’t response easily to large quantitative contrasts in policy efficiency when described in the abstract.
Further, people seem even less sensitive to policy efficiency when they *moralise* the issue highly: they'll support almost any policy scenarios aiming to reduce CO2 emissions...

high efficiency policies at least 40 times more impactful than low efficiency policies--and hugely profitable by a hundred million euros rather than costing this amount--received only a bit more support than low efficiency policies.

🔷 First, hyper-sensitive dispositions to detect threat, from social threats in particular.
🔷 Second, motivations to try to keep people *mobilized* for moral causes and against dangerous groups, by controlling information flows and beliefs. Basically, a policing motivation.

🔥 All political movements, left and right, engage in speech repression when it favours their interests and worldviews, or offers status-enhancement opportunities. Even those claiming to be “pro-freedom”. The default is a state of *moral hypocrisy*.

With the same unbelievable courage, Daryl Davis has approached, befriended, and caused tens of KKK members to leave the klan. Here's an awesome interview in which he details his approach with Yascha Mounk:

With breath-taking courage, Deeyah approached the racists in their homes to film them. By showing them respect and empathy, and asking the right questions, she gets them to feel dissonance, to realise their hateful generalisations make no sense. To watch urgently if you haven't.

Deeyah Khan just released on YouTube her magnificent documentary on the US "neonazis" (Meeting the enemy, 2017). It is one of the most moving and important documents there is out there about political hatred and how to reduce it: www.youtube.com/watch?v=hvt5...

*Why is it taboo to publicly express discriminatory or "dangerous" statements? A "common knowledge" approach.*
In all human societies, there exist "taboo" statements and topics in the sense that their public expression causes fear or is strongly morally disapproved of.

I seem to see what I’d like to call the “jihadism-in-Gaza” fallacy in how some informed people discuss the conflict. What do you think?

Dealing with an ingroup (vs. outgroup) audience systematically increased intentions to share news congruent to the user and her audience (i.e., it amplified partisan sharing).

Study 1 provides a first external validity shot. Using data on news domains shared on the US Twitter in 2019, it shows that Twitter users engage in partisan sharing only when, and all the more as, they perceive their (real) followers as being somewhat to definitely likeminded.
