If we were only writing fact, half of this Wiki wouldn't exist - That said, anything not (yet) supported by evidence must of course be formulated as being speculation.

Then there are two possibilities:

- either completely delete what has been proven wrong

- or edit it to show it's been disproven yet let the original assumption stand.

The latter is the more lively way, as it shows the development process, which can be quite interesting compared to a sober fact assemply.
