A reason persuasion is surprisingly difficult - stroke leaders?

Knowing how to do this in stroke is imperative. We have to somehow convince everyone in stroke leadership positions that they have no clue in how to solve anything in stroke.
Another great Seth Godin blog post.

Each of us understands that different people are swayed by different sorts of arguments, based on different ways of viewing the world. That seems sort of obvious. A toddler might want an orange juice because it's sweet, not because she's trying to avoid scurvy, which might be the argument that moves an intellectual but vitamin-starved sailor to take action.
So far, so good.
The difficult part is this: Even when people making an argument know this, they don't like making an argument that appeals to the other person's alternative worldview.
This is key. What is the worldview of stroke leaders that they don't see all the problems in stroke and just focus on press releases, prevention tidbits and F.A.S.T.?
Worth a full stop here. Even when people have an argument about a political action they want someone else to adopt, or a product they want them to buy, they hesitate to make that argument with empathy. Instead, they default to talking about why they believe it.
