I'd be much more comfortable answering the probability sections if I knew what epsilon is. I usually say 0% when the value is less than 0.5% and 100% when the value is greater than 99.5%, rounding to the nearest whole percentage, on the grounds that the whole point of using percentages is to avoid explicit fractions (common or decimal). But then you ruin this by explicitly mentioning 0.5% and 99.99% as possible answers. If you had put a hard limit on the number of digits allowed, then I could have used that. In the end, since I saw no consistent guidance, I fell back on my usual practice. The result is that I had a lot of 0s and 100s; hopefully that won't mess up your algorithms.

ETA: It is probably relevant here that I am a naturally lazy person.

I think it might have been better to ask people to estimate what are the odds that a given statement is true. If a probability of a statement is close to zero or close to one, it gives us better precision without having to worry about digits after the decimal point (however, if a probability is close to one half, it is probably better to ask for a probability). Although it is easy to convert odds to probabilities, how many people in this survey actually took the mental effort to remind themselves to calculate the odds first and only then to express them as probabilities? I might be wrong, but I guess that only a minority. An idea for the next year survey - it might be interesting to compare the answers of two groups, one of which would be asked to estimate probabilities, the other one to estimate the odds.

First thing I thought was ‘I'm not sure it's accurately calibrated’, but since we're measuring ratios it doesn't matter.

Took the survey. However, my answer for the probability of MWI is "Since MWI makes the same predictions as the standard interpretation, asking for the probability of MWI is meaningless. It is like asking "this glass is 50% full of water. What is the probability that it is half empty? What is the probability that it is half full?" I put 0 for the MWI question, but I'm not sure what you want for that.

For some of the other probability questions, my answer is "I don't have enough information to come up with a good estimate, and I also don't have enough information to come up with a probability that takes into account my inability to come up with a good estimate". Again, I put 0.

Also, after the test, I'm starting to get worried how you anonymize the questions. Releasing the data without a name attached is not anonymization, if the answers people give are enough to identify them.

Sure. If I pick the same spot I get the same results. Esp. with a photocopy. But at least the significant difference between left and right hand remains. Even when photocopying it makes a difference how strong you press your hand against the plate and how much contrast the scan has (for me it was too dark to make out the creases clearly).

You're assuming the answer I wrote down was an accurate name of a bone.

Largest is ambiguous. It could mean longest, or largest volume (with or without counting the volume enclosed, if we're talking about the skull), or even heaviest.

Done! Wish I had had a scanner handy going in, I'm curious about the digit ratio.

For me its not even the second digit. Even left and right hand differ significantly. Copire doesn't make things really better (OK, the copier quality was low, much too dark).

Took it.

EDIT: I was surprised to find the BEM test in it. I took it some time ago and it resulted in 65-70% F and 50-60% M (as far as I can see largely because of my strong and caring relationship to my children).

I didn't determine my digit-ratio during the test but did right now. I arrive at totally different values (between 0.91 and 1.05) depending and hand and exact points and the copier print reading gives still different values. My best guess is that it is somewhere around 0.96.
