To me, bubble sort is intuitive, as far as sorting algorithms or their detailed implementations go. I absolutely wouldn't sort that way if I were to sort something as a human, but in that case I wouldn't be even trying to figure out an exact systematic logic with its minute details that always gets it right. I'd be thinking in terms of ad hoc problem solving, and possibly some heuristics for speeding it up. When thinking of algorithms in a programming (or CS) sense, getting the exact logic right down to the detail is exactly what you'll need to do. So, to me, those aren't the same kind of intuitive. As is probably common, a bunch of simple sorting algorithms were given as some kinds of introductory examples of algorithms during my first university programming courses. I think those included selection sort, bubble sort and insertion sort. I don't think I initially considered bubble sort the more intuitive one (I think selection sort was it for me). But for some reason, over the years the basic logic of bubble sort became more obvious to me than those other options. So, at least personally, maybe there's something else to it than following the herd. Of course I've never actually written bubble sort in any kind of real code, but it's still perhaps the most intuitive one to me, in terms of detailed algorithms rather than in terms of heuristics for human problem solving. (Merge sort is also about as intuitive to me at least as a general idea.)
