Hello Codeforces,

I hope everyone is having a great day.

Recently I have been seeing many articles and journals on whether certain skills are inherent or acquired. These articles talk about whether, for a certain skill, one is simply born good at it, or someone works to develop this skill, and over time builds it.

According to R. Plomin, (https://www.scientificamerican.com/article/is-intelligence-hereditary/), genetic differences account for a shocking 50% of cognitive disparity among people. The rest is affected by factors like environment and pure hard work.

Does this mean that those who draw a good hand of cards are more likely to be successful?

Let’s get more specific.

In a study done by the University of Washington, (https://www.sciencedaily.com/releases/2020/03/200302103735.htm), participants “took eight different tests: one that specifically covered numeracy; one that measured language aptitude; and others that assessed attention, problem-solving and memory.”(University of Washington, 2020). After, the participants learned Python for 10 45 minute sessions on Codecademy, taking tests along the way. At the end, 70% of the variability between test scores was able to be explained using the original scores of language aptitude and fluid reasoning.

Although this test was just over a short time period, it accentuates how learning to program may be easier for those with certain innate qualities.

Combining these two notions, I wanted to see, Is CP ability innate or acquired? To test this, I would like to compare participants' IQ with their CF rating and see if there is a direct correlation between IQ and CF rating. To assess this, I will be using the online IQ test at https://openpsychometrics.org/tests/FSIQ/. This test has three sections, Memory, Verbal, and Spatial. Upon the completion of the test (which takes around 5-20 minutes), fill the form at https://forms.gle/wJsq9U52z1H1bCsU8. Remember to copy-paste the URL of the end screen into the response. When I reach 50 responses or more, I will begin plugging the data into Microsoft Excel and will make another blog with the results.

UPDATE: The submission window is now closed. Thank you to everyone who submitted, I have received over 170 responses. I have begun my analysis, expect a subsequent blog post within the next couple of days.

UPDATE 2: The update blog is now posted. https://codeforces.com/blog/entry/91237

 » 6 months ago, # |   0 "There is not much benefit to taking a super long time on the test, but if you speed through in less than 10 minutes your scores will be much lower than they would otherwise be" Can you tell why is it so?
•  » » 6 months ago, # ^ |   +11 I did not create the test, but I would assume it would be because spending less time on the test would mean not thinking through each question fully, generally resulting in a lower score.
 » 6 months ago, # |   +133 Maybe I don't know much but can the below question really decide my IQ ?I mean according to me IQ is all about some creativity...not some memorizing stuff.
•  » » 6 months ago, # ^ |   -31 I would think that how well your brain memorized and retains information is definitely a measure brain function in some capacity. Also, for non-English speakers, I know that some aspects of the test will the harder than others, a reason why I ask for whether the participant is fluent in English on the form.
 » 6 months ago, # | ← Rev. 3 →   -11 No relation. Human intelligence is not binary (means if you aren't good at something then it does not implies you are dumb).Mark Zuckerberg was just green on topcoder (link) but is in no way less smart than red coders here.Another example is Prof. Danny.

 » 6 months ago, # |   +6 ¿ Expert > 110 IQ, Candidate Master > 120 IQ and Master > 130 IQ ?
•  » » 6 months ago, # ^ |   0 pulsatio Can you please tell me your scores in MEMORY test and SPATIAL test?
•  » » » 6 months ago, # ^ |   +9 In fact, in past tests I had 135 IQ, but the comment is sarcasm. I don't think it's that measurable.
•  » » 6 months ago, # ^ |   -8 May be! Mine was 117. What about u?
•  » » 6 months ago, # ^ |   +8 https://openpsychometrics.org/tests/FSIQ/results.php?data=MsRRKuNXkhCQMaster, here I come!sarcasm sarcasmMy prediction: maybe a very weak correlation, CP is more about dedication and practice than innate ability.
•  » » » 6 months ago, # ^ |   0 yeah bro, anyone with skills can get to grandmaster, the comment was sarcasm
•  » » 6 months ago, # ^ |   +74 it says my IQ is <70
 » 6 months ago, # |   0 My Full Scale IQ is only 107! I was too bad at verbal IQ test as I'm not a native English speaker and I hated vocabulary. Now I know why I'm still struggling to even become a specialist. Verbal IQ — 85 Memory IQ — 127 Spatial IQ — 121Now I'm regretting for taking this test. :(
•  » » 6 months ago, # ^ |   0 The three sections will be evaluated separately. It doesn’t matter if one of your categories weren’t as strong as the other ones.
•  » » 6 months ago, # ^ |   +1 The results shown by the test is not why you're struggling to be a specialist.
•  » » 6 months ago, # ^ |   0 100 is average. Are you saying an average person is not 'capable' enough to become specialist? I doubt it. It's about how long it takes to get there.
 » 6 months ago, # |   0 It seems that your memory score heavily contributes to your overall score. Proof: https://openpsychometrics.org/tests/FSIQ/results.php?data=KXpTlFBAMpdaI think we should rather analyze logical thinking and pattern recognition abilities as this seems much more important than memory for CP. I would suggest to use mensa online iq test's for your analysis, as they are mostly based on deductive / inductive reasoning. For example: https://mensa.dk/iqtest/
•  » » 6 months ago, # ^ |   0 The IQ test chosen was standard and I am aware it does not exactly align with CP and the skills needed for CP. After all, there would obviously be a strong correlation between a test that is like CP, and CP skill, however, it would be interesting to see the results using a different, more CP-related test.
 » 6 months ago, # |   +6 There is an aproximation that says to gain real mastership at anything we need to work for 10000 hours on that topic.This is certainly a somewhat arbitrary value, but the core of the statement is: The level that is reached after this time is close to what is achievable at all.Also is true, that most of the 100% we could reach will be reached in a much shorter time.That yields the conclusion that after two or three years of hard work there is not much more potential. And that seems true given the majority of rating graphs.

 » 6 months ago, # |   +3 Hey, I think it is insufficient to ask for the URL of the analysis screen. For me, the URL looks like this:https://openpsychometrics.org/tests/FSIQ/results.php?data=Notice that there is no base64 string after data= that I see some people have. Instead, it seems that it sends my test results with the POST form data. This is what the final result screen request looks like.
•  » » 6 months ago, # ^ |   0 Oh, I don't know why that problem is coming up. I use Google Chrome browser, and maybe it does not work on firefox. In this case, I would say just submit a link to a screenshot of your scores for each category, and your overall score. This can be done by google drive or imgur, or anything where I can access the link. Thank you for noticing this.
 » 6 months ago, # | ← Rev. 8 →   0 I think IQ has to do more with the pace of improvement than rating...lesser time required to gain the same amount of skill.Edit: I meant hard work not time.
•  » » 6 months ago, # ^ |   +6 Look at Benq for example
 » 6 months ago, # | ← Rev. 2 →   +1 IMO they don't correlate much as I got 135 IQ in the testhttps://openpsychometrics.org/tests/FSIQ/results.php?data=8nJsXdwXmHVn
•  » » 6 months ago, # ^ |   0 That just means you are destined to be very high rated. orz Also, outliers will be there, the reason I'm using a relatively large sample size.
 » 6 months ago, # |   +93 Looks like I have the verbal intelligence of a rock, have fun with the outlier :)
•  » » 6 months ago, # ^ |   +2 I would call the verbal iq score nearly completely useless, especially if english is not your first language. I fail to see how knowledge of more obscure words correlate to higher iq.
•  » » » 6 months ago, # ^ |   0 On the form, I ask if the participant is fluent in English or not for that reason.
 » 6 months ago, # |   +55 Those mental rotations were really fun!
 » 6 months ago, # |   +5 Correlation between CF rating and IQ?Sorry i can't help .My IQ and Cf ratings are not in good terms.They broke up after being in a complex relationship for 1-2 days.
 » 6 months ago, # |   +16 A lot of the people here do not have English as their first language or second language and their skill in English varies quite a lot, I think it is better if this experiment is carried out using any other online IQ Test which is not language specific and just tests Spatial and Non-verbal Reasoning.
 » 6 months ago, # | ← Rev. 6 →   0 I think I did ok, verbal killed me or I thought it did lol..Memory : 117Verbal : 115Spatial : 132Result:https://openpsychometrics.org/tests/FSIQ/results.php?data=ll6wcePFDakuAlso now I know why I have high spatial IQ, notice anything here ?: https://ibb.co/Bs3RzDQ
•  » » 6 months ago, # ^ | ← Rev. 2 →   0 Verbal destroyed everyone... Lolyours verbal is pretty impressive if you're not a native english speaker have a look at mineIt's fucking 92.
•  » » » 6 months ago, # ^ |   0 Yeah I am not a native english speaker.
 » 6 months ago, # |   +11 There's correlation of course but I think IQ will usually tell you how fast you'll make progress. To become really good you have to put in a lot of work, and doing that requires motivation. There are different reasons why people are motivated to do CP.Even disregarding the verbal score, this is still nothing special, everyone meets more intelligent people every day. My z-score on Codeforces is actually significantly higher than the IQ score I got, which should tell you I put in a ton of work.
•  » » 6 months ago, # ^ | ← Rev. 2 →   0 I said the same and got downvoted :(
•  » » 6 months ago, # ^ |   0 I expect a strong correlation because CP test a lot of the same skills as IQ tests. Implementation problems with ton of details that you have to keep in short term memory, pattern matching for previously seen stuff in long term memory, manipulating data structures and indices in spatial memory, fast reading comprehension, etc.

 » 6 months ago, # |   0 Results SpoilerI really liked the closest distance questions.
 » 6 months ago, # |   +1 My resultreally hard for a not native English.
 » 6 months ago, # |   0 There are two obvious problems with this test1- It only measures verbal and spatial intelligence whereas competitive programming ability is likely most strongly correlated with numerical/mathematical intelligence. 2- A vast majority of CodeForces users are non-native speakers so the verbal portion of the test will not reflect their true abilities.

 » 6 months ago, # | ← Rev. 3 →   0 Guess I'm a bit late. Consider my results as well for any future analysisMemory — 126Verbal — 118Spatial — 141
 » 6 months ago, # |   0 I'm not sure about the validity of this test. Don't trust online IQ tests. Instead, you should have asked for scores from legitimate IQ tests such as the WISC-V and the Stanford-Binet 5.
