Orchids with a strong scent

I'm going to have to disagree that scent is deeply personal. There are undoubtedly people who could not smell certain scents like there are people who are color-blind. But the molecules that cause the scents are there regardless. If there are molecules in similar constitution to the molecule emitted by chocolate, and two people have experienced both chocolate and the orchid, then they could make that connection in the same way it would be if two people saw the same landmark or tasted the same dish.

There's a chance that one person is blind and didn't see the landmark, but get enough people together and there will be corroboration.

I think we can all agree that perception is subjective, but there's nothing special about scent that doesn't apply to every other sense.
