The ranking is 'countries prepared' to pay bribes, which is an altogether different thing from saying countries where people do.

Like Brit, I would have thought that Nigeria would have been on the list, but perhaps that's because India, China etc are countries where people pay bribes without hesitation, whereas Nigeria is a country where people pay bribes, but only after some hesitation.

I.e. in India 70% of people are prepared to pay bribes, but in Nigeria 30% of people are prepared to pay bribes immediately when asked, even though 90% of people eventually do pay them.

Just thought.
