Another month has passed and here is a new rationality quotes thread. The usual rules are:
- Please post all quotes separately, so that they can be upvoted or downvoted separately. (If they are strongly related, reply to your own comments. If strongly ordered, then go ahead and post them together.)
- Do not quote yourself.
- Do not quote from Less Wrong itself, HPMoR, Eliezer Yudkowsky, or Robin Hanson. If you'd like to revive an old quote from one of those sources, please do so here.
- No more than 5 quotes per person per monthly thread, please.
- Provide sufficient information (URL, title, date, page number, etc.) to enable a reader to find the place where you read the quote, or its original source if available. Do not quote with only a name.
There's probably cultural context you're missing (I'm guessing you're not a native English speaker, or at least non-American.), because it's pretty straightforward from here without any textual context.
A "good loser" is idiomatically someone who can accept defeat graciously (i.e. not get bitter or angry at the opponent). The quote says that anyone who doesn't get offended by their own losses won't improve and will remain a loser.
I think being a good loser is more than that. Not investing more resources into a losing project because of the sunk cost bias is on of the things is a skill that makes someone a good loser.
