As a follow up example on my last post on reasonable equivalence, consider this example. Before anyone boards an airplane, all the seats within a given class (e.g. coach) are considered reasonably equivalent. This is why I can go up to the gate agent before boarding begins and request a different seat (such as a window, or one closer to the front of the plane) and they will accomodate me if they can.
However once I board the plane and I'm settled into my seat next to my traveling partner with my carry on stowed in the overhead above me, my shoes off, my book out, and my earplugs in, I really have no desire to swap seats with anyone else on the plane. Despite the fact that any other seat remains reasonably equivalent, there are now significant switching costs that must be factored in. If I were in some way compensated for my trouble (e.g. upgraded to first class), or if the switching cost is low (e.g. swapping my aisle seat with the person at the window) I might be enticed to trade. But the important thing is this is my choice. I am not required to.
So Bullis Charter School supporters, please stop asking to swap your site with a different one in the district. Unless you are willing and able to offer compensation to offset the switching costs, it's simply not going to happen.
