while you can (already) add a fixme tag, I fear that creating a special feature for less reliable information could lead to people being encouraged to adding more “guess work” because they “set the unreliable flag so what’s the problem?“

I just had an idea: You could calculate a reliability index for each and every object in OpenStreetMap (and maybe for each of their tags, by looking at the mapping experience of the person that added it. In a more complex iteration, it could also take the reliability of specific mappers into account by analyzing whether things they add or modify are kept or changed by following mappers (and it would probably have to take time into account, because if something is changed after a long time it is more probable that it was because of a change in the real life and not because of bad representation, and maybe also the kind of change). It could also be done according to the field of thing (e.g. this mapper does reliable work with buildings or this mapper is an expert for outdoor routes but does poor work in cities, or is an expert for railways, etc. etc.)

There is a lot of stuff that could be analyzed, immense. All the history is still available with all the user information...
