There was a "protect kids self-esteem" bit, but that was entirely at the top end - there was no trophy saying "First Place". I certainly never saw trophies 'celebrating' losses.
More broadly, though, I definitely remember ignoring all of this stuff as a kid. We weren't allowed to keep score during soccer games because it "wasn't about winners and losers". (One wonders why we were playing a competitive sport, then.) Not just "score wasn't kept" but "get in trouble if you're heard talking about score".
So... we had to keep score when coaches and refs weren't in earshot. That was the entirety of the result. If anything, it sort of felt like something we did to protect the fragile adults! After all, the winners still made fun of the losers every game, nothing had changed, but now the adults didn't have to see it happen.
"We don't keep score, there's no winners and losers, but if we win this game we make the postseason."
I agree that this has been blown out of proportion, as csydas said in the parent comment. Criticising participation trophies is mostly a way for certain people to signal that they don't buy in to "all that millennial snowflake bullshit". How much harm can it really do?
Having said all that, having to play soccer while secretly keeping score does sound crazy!
Kids are pretty smart (way smarter than some people/parents think they are) and they know how far they can go, and what they can get away with.
A participation ribbon might well have motivated me at age 6, and frankly I doubt both the morality and common sense of anyone saying a six year old is too happy at a swim class. Keeping kids involved at that age seems like the biggest goal.
On the other hand, I have annoyed memories of getting participation ribbons at 15 for doing terribly in races. They felt downright insulting, because I knew exactly how I'd done and I was basically getting a ribbon for taking a bus to the meet.
A shocking number of educational issues seem to boil down to "6 year olds are not 15 year olds". That, and "offering things is better than enforcing them" - participation ribbons are way better than banning score-keeping, which I also got to see.
I think the natural bias to put discrete values on things existing on a spectrum is where is all stems from. "We want to keep things simple, so here's this recipe for self-esteem" as opposed to "here's an age-based breakdown of ways to build self-esteem". Even then, the "enlightened" example is missing loads of other conditions, like if the person suffered emotional abuse or has automatic negative thoughts.
Also, banning score-keeping is the naive approach. I think an interesting one would be to add a game score & encourage both teams to collaborate to increase it. I don't know how it'd effect things, but it'd be fun to find out!
I time the runs myself on my phone so the email has little real purpose, but for some reason it's very satisfying to know that my efforts have been logged in a database.
I'm unlikely to ever hit the top 20, so this is very much a participation trophy. Maybe they can be motivating after all?
(Take with a grain of salt. My only experiences with raising children involve raising myself & my parents over the past 1.5 years.)
See for example the https://en.wikipedia.org/wiki/Lanterne_rouge .
I've never heard anyone say "the school gave my kid a 14th place ribbon, how cute!". It's always "can you believe they give out ribbons for 14th place now?!"
Kids are pretty astute at picking up on this stuff, and I expect that being given a 14th place ribbon just feels a little sad and pathetic to a kid.
It probably doesn't do any real harm either, apart from contributing to landfill waste!
