Why aren’t more people 'factful'?

I'll add a bit more here (and Rosling was talking here about climate change).

And whenever we talk about the future we should be open and clear about the level of uncertainty involved. We should not pick the most dramatic estimates and show a worst-case scenario as if it were certain… We should ideally show a mid-forecast, and also a range of alternative possibilities, from best to worst. If we have to round the numbers we should round to our disadvantage. This protects our reputations and means we never give people a reason to top listening.

In fact, perhaps because he takes the IPCC reports seriously, he does think climate change is a problem. But he thinks, correctly, that Al Gore has done harm to possible solutions to the 'problem' because he exaggerates.

This is another really good book, one that offers a way forward to people who worry too much about the world they live in. Human progress has been quite fast in the last half-century, and shows every sign of continuing. In the next essay I'll spell out, in summary form, what the advances have been. They are staggering. And I'll bet most readers will not know most of them.
