I thought about it and adapted the image Joel linked to and came up with a new image that shows a number of cylinders on a field of light and dark squares.
Using the cylinder labeled "A" as a reference, and using your powers of absolute judgement, which of the numbered cylinders is the most similar to "A"? Which is the most different?
Please post a Comment and express your answer as a two-digit number, the first being the number of the cylinder that is the most like "A" and the second the number of the most different from "A". (Of course, also say if you have Liberal or Conservative tendencies.) If you wish, I'd appreciate it you tell us how you came to these conclusions.
Joel wrote, in part: "When I started studying my concept of inborn L/C-minds, I hoped that I could find a simple non-political discriminator. It would be interesting to find an optical illusion that would do this. The trouble with most of them is that they are universal. ... It would be wonderful if L-minds saw one and C-minds saw the other at least at first glance. That would be proof of a wiring difference unconnected to education."
A few days from now, I will update this posting and indicate why I think this might possibly be a valid test of L- vs C-minded tendencies (or not :^).
TRUTH [the following was added July 14th]
The image below shows the "truth" about the five numbered cylinders as they relate to cylinder "A". Spoiler - Don't scroll down to the image unless you have thought about the issue for a while.
As Joel and Howard noted in their Comments, at first glance, "51" appears to be the answer. Cylinder "5" looks most like "A" in shading and size and "1" looks least like "A", much lighter in shading.
However, further "logical" consideration reveals some problems with that initial conclusion. The cylinders do not seem to conform to the laws of illumination. How can a cylinder in the shadow of the larger green cylinder have a bright top? Also, Howard remembered the base image is an optical illusion and the squares behind "A" and "3" are actually the same exact shade. Thus, since neither cylinder "A" nor "3" have a left edge, their left sides must also be the same exact shade.
So, how does this relate to L/C minds?
IRA'S L/C MIND THEORY
I have a theory that we each have both an L-mind and a C-mind, and we learn to use each of them to maximum advantage. We need both to survive and prosper in the real world.
Our L-mind is "warm-hearted" and "instinctual". Our C-mind is "hard-nosed" and "logical". Those of us with L-minded tendencies, tend to use more of that side of our intellect and vice-versa for those of us with C-minded tendencies.
For example, most L-minds would subscribe to Benjamin Franklin's notion that "it is better a hundred guilty persons should escape than one innocent person should suffer". Our L-mind imagines the anguish we would feel if we were wrongly convicted of a crime and sent to rot in jail.
Most C-minds would ask "Why 100? Why not 1000 (Maimonides)? Or 10 (Blackstone)? Or 1 (Trajan)? Should the number be higher or lower for capital cases?" A C-mind would inquire as to the recidivism rate: "How many of the hundred guilty would in future commit crimes that victimize other innocent persons?" Our C-mind imagines the anguish we would feel if we, or other innocents, were victimized by a guilty person who had previously been aprehended and tried for a serious crime but had been set free due to a crafty lawyer or some technicality.
In many situations it is important to react "instinctually" - "kill or be killed". In many other situations we have the time and resources to act more "logically" - "checks and balances". My point is that L-minds tend to react "from the heart" while C-minds "from the head". I thought my optical illusion problem might separate the two.
SO, WHAT IS THE TRUTH"
Back to the image! After logical consideration, it is clear that the instinctual "51" cannot be correct. There is something out of place about all the small cylinders. Those in the shadow of the large green cylinder should not have bright right sides, yet they do. Those outside the shadow of the large green cylinder should cast shadows of their own and yet they do not.
Clearly, these small cylinders are not in the original optical illusion image, but have simply been pluncked down in front of the image to confuse the viewer. Take them out of that image and put them on a uniform white background and the truth will come to the fore.
Cylinder "3" is identical to "A". Cylinder "4" is both larger and darker, so it is the most different. Thus, the correct answer is "34".
