Effective altruism is a complicated idea. When an idea is complicated, often people don't understand the full idea but instead some low resolution version of the idea which they get from snippets of conversation, impressions they have from other people, and vague recollection of media articles.
What's the current low resolution version of effective altruism? Is it positive? What would a better low resolution image be?
I find others answers about what the actual low resolution version of EA they see in the wild fascinating.
I go with the classic and if people ask I give them a three word answer: "doing good better".
If they ask for more, it's something like: "People want to do good in the world, and some good doing efforts produce better outcomes than others. EA is about figuring out how to get the best outcomes (or the largest positive impact) for time/money/effort relative to what a person thinks is important."
