I noticed this while using websites that require login/logout - I get used to accessing the "Logout" button at the bottom of the menu. For example:
On burger menu, the logout option will always be at the bottom, and usually the top row of the menu is mostly "Details" or "Account Info."
Last night, I opened Steam website and I clicked the ">" button to extend the menu. The layout is a bit different, and I accidentally clicked the "Logout" button by reflex, because (by habit) I thought it was a "Details" menu because the link is on the first row. Here's a screenshot:
So yeah, I'm not used to the "Logout" button/link being at the very top of this kind of menu. It got me wondering, my question is:
What is the base theory for this position of the "Logout" button in menus with rows? Should it always at the 'end' because it shows the exit sign (technically)? And why, for example, does the Steam website place the "Logout" button in the opposite position? Is it something to do with other habits or tendencies?
PS: Pardon my English, I try to articulate my thoughts in limited grammar.
