Do raised toilet seats make it harder to poop?

 I am surprised and find it hard to believe that raised toilet seats increase constipation or make it harder to poop.

I have found through undesired research that not bending all the way down, as if you have a raised seat, makes it much easier to complete emptying the colon. I found multiple sources that contradict apparent first hand evidence. It not implausible to me that the standard American toilet seat height is near the worst possible height and the Squatty Potty makes it easier and the opposite, a raised seat, also makes it easier than the standard American toilet seat height. It's conceivable my subjective kinesthetic sense is inaccurate as to the angles involved. The sensing is being done in a time of high stress. Do you believe that extra high toilet seats, perhaps tilted so they're higher in the back than the front, would or do make it harder to go?
