OP's point is that this isn't valid because neither of the answers are correct. If you're really trying to measure a spectrum then the answers should allow for fuzziness. That is, you have a range/confidence interval of where green ends and where blue starts and in between is neither/both.

[reactordev]

correctness is not the point. binary choice is the whole point. because my blue may not be your blue...

[eikenberry]

It should probably alternate between blue/notblue... green/notgreen. I hit the same wall. Second question asked if blue/green when it was neither... and I really mean neither. I don't see cyan as a shade of blue or green, rather much like I don't see green as a shade of blue or yellow.

[arcfour]

Huh. I consider cyan to be blue, but it turns out it's made by mixing equal parts of blue and green light on an RGB display.

I guess that makes sense thinking about it now since it's not a deep blue, and there's obviously no red component, but I never thought of it as being defined as equal parts blue and green.

(Turquoise I would consider to be blue-green/both).

[p1necone]

yeah I've always thought of cyan as just "blue, but really bright", which does make sense - you're going from 0, 0, 100 (blue) to 0, 100, 100 (cyan) so it's twice as far from pure black. I also see pure cyan as being much more blue than green.

There's no way for me to answer truthfully whether teal is blue or green. It is neither. Anything I give gives a false answer. The data is invalid.

[pibaker]

How would you feel about a test for "teal or blue" or "teal or green?" You still need to make binary choices, just along different boundaries. Would it make any difference?

[jstanley]

How would you feel if the site showed you red and asked if it was blue or green?

[ajkjk]

if the question was "is this more blue or more green" it would be somewhat more agreeable. but there really just have to be a "can't decide" option as well.

[reactordev]

Incorrect, it either lies on the blue side or the green side, you must choose. Neither is not an option.

[xmprt]

If you gave me the exact same color code 20 times I might give you green 10 times and blue the other 10 because I genuinely can't tell the difference. So it's not a binary like you're claiming.

[reactordev]

If you did that, your score would be 50%, that’s how this works.

[t-writescode]

Sometimes the answer can be “I reject the premise.”

I’m sure you’ve had conversations where that’s the answer you want to give.

[ajkjk]

I chose to close the tab.

[svnt]

But reproducibility should be the point. As a result of the structure it approaches an asymptote from one side or the other. I took it once and approached from green and my greenness was 77%, a second time it approached from blue and my blueness was 68%.

A test that allows an answer of neither would deliver more information (transition points and an error bar) without failing to identify a distribution in the population taking the test.

[ImprovedSilence]

It's so remarkable how many people here refuse to understand your point. It's like, there is no right or wrong, no perfect score, just pure subjectiveness, and they can't handle it. If I wasn't convinced this site is entirely bots before, I might be now....

[reactordev]

It is enlightening to see who has been fixed on math proofs as testing and who has been exposed to observational testing. Seems many people have been brain washed into the former, forgetting the latter exists.

[Suppafly]

>correctness is not the point. binary choice is the whole point. because my blue may not be your blue...

Realistically there is a broad range that we all can acknowledge is neither, but is instead teal, and forcing a binary choice means people just choose randomly.

[housecarpenter]

I don't think that's necessarily the case. I understand that there's a continuum in reality, but psychologically, I still tend to perceive each shade as discretely either blue or green, especially when the shade is presented in isolation. Words like "teal", "cyan", etc. aren't really part of my normal vocabulary and to the extent that they are, I would think of them as subsets of blue or green, not disjoint sets.

I think the test can be fairly criticised on the basis that it is assuming everyone's psychological colour space has a discrete boundary between blue and green, which clearly isn't the case for some people (like you), but it is for others (like me).
