Why does everyone believe losing is a learning experience?

Quite simply, you learn from your mistakes. In boxing, in everything. If you don't, you continue to lose.

 

Because a lot of times only in defeat will you find out your true weaknesses.
To become the best or to push yourself to the absolute limit of your true potential you will come unstuck somewhere along the line,then its a case of working on the weaknesses and coming back stronger.
Morales whooped pac in their 1st fight,pac was a one armed fighter,still good but after the 1st morales fight was a massive turning point,after that fight he developed more punches in his arsenal and he was a far better fighter after it for the loss.
Leonard come back better after the 1st duran fight and so on.

 

If this is the case if nothing else you learn your level.obviously not everyone can reach the pinnacle.with work on certain areas you can always come back stronger.

 

That's why you need to be matched with guys who are just a bit better than you, but not by that much. Then you can develop and learn from mistakes.

Psychologists call it the "learning zone": “Identifying the learning zone and then forcing oneself to stay continually in it as it changes are the first and most important characteristics of deliberate practice.” Talent is Overrated, page 69

If you get beat by a guy who is 10x better than you it is not a learning experience. Just like beating a guy who is just as good as you won't help you develop by much. Losing to a guy who is 5-10% better than you however can be a tremendous learning experience.

 

no way fighters learn from losses they learn from wins they learn from each and every fight. and if you dont learn nothing in that sparring session that your gettin your ass beat well quite honestly you should. you should have some one telling you what you did wrong. unless the person is so just so much far superior then there is just nothing you can do . and if your in the ring with that guy and the coaches there are letting this guy in the ring with u a huge mismatch i dont think a good gym would let that go on .

i learn something from my ass beating thats for sure. main reason i get caught with a flurry of puncning cuz i dont move !! usually on or near ropes. you just gotta no how to get out of there.

 

If someone is using distancing or exposing a flaw of yours and the fighter still has a few years of career left he can definitely still adjust his style and learn from the experience. If they get knocked out due to exhaustion, they need to either work on stamina or energy expenditure. Most of the time when guys start losing they are at the end of the career so they can't really learn THAT many new things or improve that much.
