It's a fact that certain movies do better at certain times of the year
We hear this a lot, but I have to wonder how much actual truth there is to it. As you say, this idea is basically a tradition held over from the old days. How much actual research was done on the matter? Has anyone ever done any real controlled experiments at all or have they simply looked at what seemed to be happening, assumed that it was a fixed truth and then made up a bunch of logical-sounding arguments for why it might be the case? People are great at fooling themselves, and confirmation bias is always a big player. I wouldn't be at all surprised if this "fact" is actually no such thing at all, merely a repetition of folk lore that no-one is willing to question. Essentially it becomes a self-fulfilling claim - every knows action films do best in summer, so everyone releases their best action films in summer.
Hell, even just looking at the information easily available and not doing any admittedly risky experiments doesn't exactly support the claim. For example, horror movies are released in late summer or around Halloween. Like Alien, released in May; Friday the 13th, also released in May; Scream, released in December; Hellraiser, released in September and not on video until the next year; The Exorcist - December; Final Destination - March; Nightmare on Elm Street; 28 Days Later; Dawn of the Dead; The Birds; the list goes on. In fact, Halloween seems to be one of the few horror films that actually follows the claimed schedule. The other categories are rather less well defined (go on, give me a concise definition of "middlebrow drama" without resorting to examples), but this doesn't exactly bode well for something claimed to be fact.
