Scientific colour maps Scientific color map suite of perceptually uniform and color-blind friendly color gradients.

Personally, for diverging maps I like dark-mode ones like Berlin from @fabiocrameri.ch (again, because I'm used to blue = negative, red = positive from jet).

And for sequential I like viridis and inferno because I'm pretty basic ๐Ÿ™‚

I suspect many people like jet, mainly because it's familiar.

And there's nothing wrong with that. Aesthetics are subjective ๐Ÿ™‚

Imo that's why turbo is great; it doesn't require a huge shift in thinking if you're used to jet ๐Ÿ‘๐Ÿ‘๐Ÿ‘

Scientific colour maps โ€“ colour-blind friendly and accurate palettes The Scientific colour maps are perceptually uniform and ordered, colour-vision deficiency friendly, and freely available and citable.

4) @fabiocrameri.ch created some awesome perceptually uniform, variant-colour-vision-friendly maps.

My favourite feature of these: The *circular* ones are really good for plotting things like oscillatory phase ๐Ÿ‘๐Ÿ‘๐Ÿ‘

3) Really in love with the jet aesthetic? No fear! Folks at Google created a 'more jet than jet' colormap that solves many of the problems of the original.

2) Using MATLAB? Steal the ones from python/matplotlib (part 2)

cbrewer has nice diverging colormaps like blue-to-white-to-red or blue-to-yellow-to-red if you want to keep that aspect of jet.

These sequential colormaps are perceptually uniform and I think they're pretty.

Doing a lit search and finding many recent papers still using the jet colormap ๐Ÿ˜ญ๐Ÿ˜ญ๐Ÿ˜ญ

Please don't use this colormap for anything because it's not perceptually uniform (changes of equal size don't look equal) and not friendly to people with variant colour vision.

Looks like a great opportunity for someone with a background in brain stimulation.

Academia needs more co-operation internally, and needs to fight mistrust being sown against it externally. So little things like this are important.

Curious what the rest of you think. Have I missed anything? 4/4 end

b)
The first framing makes receiving the award feel like an *end point*. 'We worked hard for years and now we've got this. Hurrah.'

The second framing emphasises that the award is a *beginning*. 'We've been given a chance to do something important. We'll do our best. You can count on us.' 3/4

a)
The first framing centers the *competition*. 'We're the winners because we got the money. You lose.' It's zero-sum thinking.

The second framing centers the *outputs* of research. 'When the funding is done, the whole world will have this thing. Everybody wins.' Non-zero-sum 2/4

Two framings

1: We're proud of <researcher> for getting <grant> because it's prestigious and really hard to get.

2: We're proud of <researcher> for getting <grant> because it enables them to do research that's really important.

I see versions of 1 a lot but think 2 is MUCH better.

Here's why 1/4

Is the the neuroimaging community (broadly conceived) submitting to ๐—ก๐—ฒ๐˜‚๐—ฟ๐—ผ๐—ถ๐—บ๐—ฎ๐—ด๐—ฒ again?????

Not to be publication police but the shift had seemed major 1-2 years ago.
Looking at the editorial board it seems to have serious scientists once more.
Curious about thoughts of the community.

I get the main point and agree. Just have a quick question about 'r~-0.7'.

Are you saying r~-0.7 because that would mean r^2~0.49 i.e. about half the variance explained?
