It's amazing* how the numbers changed when definitions are clearly spelled out.

"Gender dysphoria is a condition where a person feels a mismatch between their biological sex and their gender identity. For example, this may mean that a biologically male individual feels strongly that they are female, or a biologically female individual feels strongly that they are male. At present, most people who wish to legally change the sex or gender recorded on their birth certificate must first receive a medical diagnosis of gender dysphoria, but it is not necessary for them to have undergone gender reassignment surgery. The Scottish Government is committed to changing the law in Scotland within the next year to allow people to legally change their gender without a medical diagnosis of gender dysphoria, provided they make a solemn declaration that they are living in their new gender and will continue to do so.
In your opinion, who should be eligible to legally change the sex or gender recorded on their birth certificate?
Anyone who makes a solemn declaration that they are living in their new gender: 20%
Only people who have been medically diagnosed with gender dysphoria: 18%
Only people who have undergone gender reassignment surgery: 21%
No-one: 19%
Don't Know / Prefer not to answer: 22%"
