How colours affect the way you think
Our world is awash with a rainbow of colours, but certain shades can have a surprising impact on our ability to concentrate, our mood and even our taste.
«And if you want a child to concentrate, you might consider painting a classroom in a vivid palette and so bolster their reading scores.»
Do we need a better understanding of 'progress'?
A growing and influential intellectual movement aims to understand why human progress happens – and how to speed it up. Garrison Lovely investigates.
How our brains cope with speaking more than one language
Speaking a second or even a third language can bring obvious advantages, but occasionally the words, grammar and even accents can get mixed up.
«our languages aren't just static throughout our lives but shifting, actively competing and interfering with each other.»
What is Refind?
Every day Refind picks 5 links from around the web for every user, tailored to the user’s interests. Picking only a handful of links means focusing on what’s relevant and useful. We favor timeless pieces—links with long shelf-lives, articles that are still relevant one month, one year, or even ten years from now. These lists of the best resources on any topic are the result of years of careful curation.
How does Refind curate?
It’s a mix of human and algorithmic curation, following a number of steps:
- We monitor 10k+ sources and 1k+ thought leaders on hundreds of topics—publications, blogs, news sites, newsletters, Substack, Medium, Twitter, etc.
- In addition, our users save links from around the web using our Save buttons and our extensions.
- Our algorithm processes 100k+ new links every day and uses external signals to find the most relevant ones, focusing on timeless pieces.
- Our community of active users gets 5 links every day, tailored to their interests. They provide feedback via implicit and explicit signals: open, read, listen, share, add to reading list, save to «Made me smarter», «More/less like this», etc.
- Our algorithm uses these internal signals to refine the selection.
- In addition, we have expert curators who manually curate niche topics.
The result: lists of the best and most useful articles on hundreds of topics.
How does Refind detect «timeless» pieces?
We focus on pieces with long shelf-lives—not news. We determine «timelessness» via a number of metrics, for example, the consumption pattern of links over time.
How many sources does Refind monitor?
