That's hilarious! Those 2% that I did better than must really be donks.
You actually did better than 70%-80% of non-expert poker players from a previous experiment in terms of accuracy, and 90% of non-expert poker players in terms of consistency.

Cliffs: I'm terrible, but at least I'm consistently terrible.
No, you're better than 70%-80%, and 90%

You did better than 11% of non-expert poker players from a previous experiment in terms of accuracy, and 4% of non-expert poker players in terms of consistency.

Am I ******ed?
Probably not. 90% and 70%-80%

Pretty sure I'm the worst score.
Had I been asked about my confidence in my answers, however, I would have guessed I would score in like the bottom 10 percentile, but not the .00.
Bottom 30%, and 60%-70%

I question the scores and/or conditions of the previous probability experiment, as I would expect to score way higher than top 82/83% of non-expert poker players (i.e. the general population.) The probability of that being correct is extremely low!

EDIT: I notice someone else above made a similar comment. I also worked out the answers in my head, and vs non-expert poker players, any competent "number sense" guy would *easily* be in the top 5%. (Speaking as an ex-teacher of mathematics and ex-poker pro.) 90% - 95% of the population have a very poor grasp of probability.
Hi handsome. 99+% for both.

Dang it, I thought I was better at probability than that!!!

Never took stats, tried to figure some on the fly, realized I had some better answers later. Oh well.

So i'm one of the most inconsistent one here .
Very curious about how this is calculated.

I think you owe it to everyone to apologise and just admit that you simply messed up the comparisons. It's fine to use an approximation but there's no excuse not to use the correct percentiles for that figure!!

How can you read everyone's responses (e.g. "I'm terrible", "Am I ******ed?", "Dang it, I thought I was better at probability than that!!!") and not feel the need to correct yourself. People have given up their time to help you and you've basically told them "Thanks, and you're really dumb."

And if you didn't realise the results were so far off, then how could you possibly not have!?

70%-80% and 90%

80%-90% and 99%

80% and 90%

90% and 70%-80%
To be more precise, 90% scores should say 90% - 99%

Hi MeleaB,

I am one of collaborators in this study responsible for programming the survey.

Thank you for your time taking the survey and kindly rectified the feedback information.

I am really sorry for the use of bad approximation in providing the feedback. The original idea was to have a guess of what general population would be like given that we only have a sample of 82 recreational poker players. The resultant approximation, however, was too much a boost in their performance scores (especially in the incoherence scores).

We didn't mean to provide misleading feedback and downplay anyone's real performances. However, the approximation doesn't serve our original purpose well and now it looks like a disastrous idea.

Adjusting the feedback scores halfway through the data collection process would create unnecessary confound in our study, which would basically create two subgroups of people whose feedback is based on different comparisons. To avoid this confound, we decided to let everyone have the same comparison, at least for the period of data collection.

In retrospect, we regret to use approximations and apology to people who have sacrificed times to take our survey. I hope the additional quantile information that Phil posted earlier can be somewhat helpful.

I also include a more detailed individual-level scatterplot of performance scores (each dot represents one participant):



Best regards,
Zhu

Definitely this is not a test of how good of a poker player you are. These questions have nothing to do with that and its not the point of the test.

Asking for ballpark intuition (was that in the instructions?) in a numerical value seems really odd though. Multiple choice with ranges would have made a lot more sense.

I'm actually kind of surprised that 2+2 is better than the recreational player for this test. Although, 2+2 probably has a number of people that can do basic math in their head and ace this. My dad could do long division in his head before you could even type it into a calculator.

Not surprised I did badly, I almost aborted after seeing the second question. No clue on some of these questions and for about 90% of them, I never once thought about them during 15 years playing NLHE. Monotone flops are rare, I know. I stop there.
Yea obviously it is not a test of how good of a poker player you are lmao. It is not a poker test. It is a probability test. In other words it is more of a logic and intelligence test than a poker ability test since it doesn't even contain a single poker question. However, a lot of what you do in poker is based on probability or at least should be. If you are bad at probability there is little chance you are an elite poker player.

I just saw this thread today and I clicked on the link in the OP. I got this same result: invitation only. I assume your survey is closed now?

I have a question regarding the inconsistency score.

Is it inconsistency between the two games, the one with the cards and the balls? Ie, if you answer 1000 to what is the likelihood of drawing three green balls, but 0 to what is the likelihood of drawing three spades, then that's the worst possible inconsistency?

Or, is it responding to questions that should equal 1000 together, but don't? Ie how many flops will contain a 7 + how many flops don't contain a seven should equal a thousand, so would it be max inconsistent if you answered 1,000 or 0 to both?

where the card and ball questions identical?
i thought they were so for me the ball question were just more thinking time too refine my answers. but iam wondering if my inconsistency score went down because i changed my answers?

And then frequently report (via multiple methods), that it is more likely that:

"Linda is a bank teller and is active in the feminist movement."

than it is that:

"Linda is a bank teller."


This is even though the more detailed description is a conjunction of two events, which cannot -- via the laws of probability -- be more likely than the constituent event that "Linda is a bank teller."

That's one that has caused a lot of debate/controversy. But there are many others.
I've always wondered though if people interpret "Linda is a bank teller" as "Linda is a bank teller ONLY and not also active in the feminist movement." It might be possible that the it is more likely, under this interpretation, that Linda is a bank teller and active in the feminist movement.

Thanks everyone for taking your time to help out.


If a mod could update the OP with this link then that would be greatly appreciated!
