I think this is an important distinction actually.
For instance let's take the example of choosing a tool for a particular job. Over time you teach yourself that tool X is best for a particular type of task, so any time you are faced with that type of task you automatically pull put tool X, without thinking about it. On the surface it looks like you're thinking and deciding very quickly but really you're just taking a shortcut.
Eventually you are faced with a task that looks on the surface like the type of task you use tool X for, so you start working. After a while it turns out that it would be best to use tool Y. Now you've wasted a bunch of time using the wrong tool because you used a shortcut to avoid thinking, instead of taking the time to think.
It's a dumb example but I think it illustrates the difference between "thinking faster" and shortcutting your thinking to reach a conclusion faster.
