Experimental Mind: Mind the gap
🔎 What I've been reading last week
If you read one article this week, let it be this one.
Build vs. Buy is a false dichotomy. You may buy some components and build others into a hybrid.
Merle van den Akker created this list of online resources to learn more about behavioural science. This is a follow-up of her books & papers post.
Blog post about Duolingo's experimentation tool for copy tests.
From one of my favorite blogs: Ness Labs.
Often misunderstood concept, so good reminder:
P-value is a probability value corresponding to the likelihood of obtaining a data value (‘test statistic’), which is at least as “extreme” as the actually observed data value (observed ‘test statistic’), under the assumption that Null Hypothesis is correct.
P-value provides an answer to: Assuming no-difference (i.e. Null Hypothesis), what is the likelihood of seeing the difference we are observing in the data.
Direct marketing is basically a vast series of behavioral science experiments performed at scale.

😎 Cool thing of the week
In 2021, Cees Bassa's camera took a photo of the Dutch sky every 15 seconds.
This image combines the 2.1 million images into a year-long keogram, showing the length of the night change during the year, the motion of the Sun and Moon, and lots and lots of clouds.
