Not all discussions lead to conclusions, right?

More so, even less discussions lead to unanimus conclusions.
Even jurys (is that the plural?) in obvious murder cases disagree, and they are talking about facts that none of them has seen fisrt hand so they are supposedly as objective as they can be.

Imagine a bunch of people of all ages, from many different countries, discussing about a keyboard
1) that some of them have seen and tried,
2) some of them would try in the future,
3) some of them could not try,
4) some of them WOULD not try even id they have the chance
5) some of them would not see at all

Recipe for disaster.
