Juliette insisted she needed a new bed; Ian prudently acquiesced. A thousand dollars later, Ian and Juliette have a new bed that Juliette hates. She claims even the slightest move Ian makes in his sleep wakes her.
I couldn't imagine a bed being that bad, so I asked if I could test it. It felt firm, just fine.
When Juliette insisted it was as wobbly as jelly, I began an experiment. I placed four cups on one side of the bed; my plan was to fill them with water then see if any spilled when I bounced on the other side. Or rather that was the plan until Juliette vetoed it.
Some people can't stand to have their irrational beliefs exposed to the cold light of science.
