Of developed countries it found that New Zealand was the most ignorant of developed countries. Most developed countries greatly overestimate the proportion of adult wealth the wealthiest 1% in their country own.
Britain is the most inaccurate (estimating it to be 59%, over twice the real figure of 23%), but France, Australia, Belgium, New Zealand and Canada are all at least 30 percentage points out of line.
A lot of countries also miscalculated how many non-religious people made up their population.
