Is there any scientific survey about this?
I could imagine an experiment like this:
- 100 people provide at least 3 times their signature (e.g. with different pens)
- Each of them gets all 3 example signatures of e.g. 2 other people and has to forge the signature.
- At least 3 different experts get one real signature and the remaining 8 ones. They have to tell which ones are real, which ones are fake. They are NOT told how many real / fake ones there are.
Was something like that done before?
