The evaluation method of the Give-a-Number task matters. See a comparison of different methods in doi.org/10.23668/psycharchives

Calculated number knowledge (y-axis) measured with the GaN task as a function of evaluation methods (x-axis)

The SNARC effect may work only with symbolic numbers. It seems to work with nonsymbolic numbers when the task requires symbolic responses, such as "smaller"-"larger", but not without them. doi.org/10.1037/xhp0001376 or thenumberworks.org/discrete_se

I like this recommendation to report confidence intervals not as 3.5 [-2.0, 8.7] but as subscripts ₋₂.₀ 3.5 ₈.₇

Not the biggest thing, jut but seems a tiny bit easier to process.

I'm finding it a little hard to work today with this in my head.

Antarctic ice extent is now 6.4 standard deviations below the mean. That is, I'm reliably told, a one in 13 billion year event.

We're about to see a lot of shit hit a lot of fans. And we are far from ready.

Business as usual is over. Politics as usual is over. We need to be putting our effort into building systems that can help us survive what greed and power and wilful blindness have wrought.

Five-knowers, six-knowers, etc., can compare only the numbers they know in the Give a Number (GaN) task – just like any other subset-knowers. Because they are subset-knowers? doi.org/10.1111/desc.13430

The free version of Slack has some challenges, namely that messages older than 90 days are hidden from users. This makes communicating about open science and building community difficult. What platforms do you like to use for informal socializing around open science? Boosts appreciated!
