"Your mind" may trick new cyclists into thinking that a cushy, wide saddle and upright position to the handlebars is the right fit because of the comfort factor. But at least with a road bicycle, that's most likely not the proper, efficient fit.
That's why I emphasize properly fitting the engine, your lower extremities, to the correct saddle position, fore/aft and height, and the correct frame size, then worry if the frame and/or stem and bars are in the right position for your upper body.
I doubt we're expressing opposing views, but I surely hope novices are not reading this thread and coming away thinking that what feels best to them in the showroom is necessarily the right, efficient fit.
