Probably because folks are programming themselves by only playing bullet or shorter time controls.
Playing a 60 minute game on chess.com

Thanks for all the comments.
I try to play slowly when I play 60 min; however, it just feels like I'm playing a blitz or a rapid game though I always like to improve my tactics.
Furthermore, I always end up having 57-58 min on the clock.
Is this an instinct to play fast or just a humans' programming?

Try to analyze all the possible lines for 10 moves. Then you'll be saying you don't have enough time.
I play 30 minute games usually and it is good for finding good moves. I feel so content after I find some moves. Of course I have reflexes too, the feeling quickly comes when opponent makes a move but after some thinking I realize there is a better move. that is only happening in long time controls. otherwise I play the first thing coming my mind and I regret it later. you have to play slower time controls until you see enough situations to decide fast. hikaru for example he saw enough and can recall positions too fast and can decide quickly. but even he makes mistakes.
I'm pretty sure I would have lost this game if I had played fast. it was a 30m and I had 7mins on my clock while opponent had 25m when it finished. This made the difference and a good example for this topic.

Try one day games for a while. You may go back and forth rather quickly for a few moves, then people go on with their day. This will force you to either ignore the game until they move or, you can use the time to study the game for a minute, hour, our 24 hours. I sometimes check the board numerous times before deciding on my next move both before and after my opponent moves. Sometimes I even come up with a good move! I think you’ll surprise yourself if you give yourself more time.

I agree, daily games are great. Another great thing about them is you can have multiple games at a time. But I do prefer 3 days time control.
@Londonlion9, I think the reason is that people are used to playing games at time controls at rapid or blitz speed. Even if someone plays 1 hour games regularly, it's hard to use all that time, because I personally find it hard to keep focus.

That’s a good point, you can play multiple games or keep it down to just one or two, it’s your choice. You can tailor your time controls to fit your schedule. I’ve played some of the really short times, but didn’t find them enjoyable; i just blunder and lose faster. Pick what works for you and Enjoy the Journey!
