Sounds like correct methodology for the thing that CPI attempts to measure.
Singapore at #4 makes for a good joke.
"We took the opinion of this random bank about how efficient it is to allocate capital in the country, which translates to how corrupt it is"
or
"We had this (ironically, corrupt) NGO make a report where they asked some unspecified number of "credentialed" economics professors at an unspecified number of unspecified universities what they think about corruption in their country."
Yes, those are actual examples of the data/methodology they provide. That's the type of data backing up their ratings.
