Some of the behaviours you include have more impact than others. How do you allow for this?

At the moment we don’t, because it’s largely a matter of opinion whether, for example, emitting CO2 does more harm to humanity than invading another country. For this reason, all the data is weighted equally when calculating the final results. Something we’re considering for later editions is a feature that allows people to input their own views on which global issues are most important, so that the website will then produce a ‘personalised’ GCI ranking based on those parameters.
