I think before we claim analyzing games is "difficult", we have to keep in mind that people have different objectives when analyzing their games or asking for help.
Some people partake in chess and these forums not to become stronger players, but to have fun or socialize. Not everyone is trying to be a Grandmaster or play "optimal" chess. I've seen many reverse bong clouds and such :-)
The learning process in general is probably poorly understood. From what I understand, active learning (doing puzzles, playing games and analyzing) is probably more efficient than passive learning (Reading books, looking at computer lines), especially for beginner players.
I also think analyzing your lichess blitz games if you are beginner is a very poor way to improve at the game if efficiency is your objective.
In behaviorism, there is a performance and learning zone. I would compare taking your time to solve puzzles, or playing a long game where you are trying to play your best chess and try out new ideas to analyze after to be the "learning zone". Blitz on lichess is the complete opposite (especially if you just care about rating points as an indicator of your improvement). As a beginner, you won't have time to process and learn. You are purely trying to perform playing whatever you know best rather than exploring what you don't know.
Back to the original post, if we are talking about character traits like "laziness" that impair the analysis or learning process we can include hubris and anything else that will generally cause a loss of objectivity.
@jupp53: it is your perspective that the way they are analyzing the games is not correct hence it being "difficult". However we have no way to tell what they want from chess and what they are "getting" from it so personally, it is difficult for me to judge them for the way they analyze (whether it is difficult or easy). I don't really like to use words like lazy because that is a judgement and we can never know who another really is because we all have their own unique set of experiences and are changing all the time. It's what makes each of us unique.
If you want to analyze "better" or make analyzing "easier", assuming you have a fixed amount of time, the best way is probably to find a coach or another player that you believe analyzes well and ask them to show you their process (analyze a game with them). Ideally the player should either be a really good and patient teacher or only slightly better than you so the experience is symbiotic but not necessary of course.
Every time, I analyze with another chess player or even play a game, I meld their unique perspective on the game into my own, making me a more diverse chess player. We, chess players, are shaped by the games we have had to privilege to play and see.
