66.94 seconds, 22 years, grad school student, I didn’t sleep last night, I don’t consume caffeine. Edit: dumb mobile formatting


Thank you everyone! I got enough input for my class. I'm really glad. Couldn't have done it without you all.


OP I see some small potential issues with the research method. My phone’s screen starts to black out in 30 seconds. If I wasn’t holding my thumb over my clock, then I could have used to game the system.


60.33 seconds (I promise I didn't cheat!) 17 High school student 9.5 hours 1/2 a cup of coffee average.


108.15s because I'm an idiot (yes, this is my real result unfortunately) 19 student 3 or so hours of sleep zero caffeine ever


51 secs (I double clicked and lost the results) 2 pm, I'm 23, not a student (4 year grad), probably 9-10 hours sleep, and no daily caffiene consumption


60.00s. there's no way that was real. I'm either really lucky or something went wrong. Age 30. not a student. Slept 9 hours, 1 cup of coffee per day. Very originally survey btw, well done. [Genuinely wtf](https://postimg.cc/FY0KQm3z)


You're actually a robot. What, nobody told you yet?


56.51 seconds, 19, yes, 7 hours, rarely consume caffeine


63 or so 51 Not a student 9 hours 1 cup of coffee a day plus a diet soda.


I did three attempts: 89 sec (I got distracted), 52 sec and 62 sec. I’m 17, in my last year of high school, I slept about 9 hours last night, but I should be sleeping right now, I’ve never had any coffee or anything else with caffeine in it


34.49s 28 Not since 2016 About 7 hours Drink 1 cup of earl gray tea/ day. Though I have to say that measuring caffeine in cups isn’t the most accurate. A cup of black tea has around 50mg caffeine vs a cup of coffee which has around 90mg. It’s like trying to measure alcohol consumption by volume of liquid consumed. 6 oz of vodka does not equal 6 oz of beer in terms alcohol content. Also, I have ADHD and have major time blindness. And doing this test about 6 years ago was actually a big part of leading to my diagnosis. Studying psychology and learning about ADHD, my professor had us do this task, but didn’t tell us not to count in our heads. I did count and came very close to 1 minute. When asked what strategies we used to estimate the time, I said “I counted in my head”, cause how else would I possible be able to estimate that. He just stared at me for a couple seconds and then it dawned on me.

57.7. I knew I was fast in the 40's What percentage do you expect to be false?


Wow you get a bell curve at 60s. Either people are cheating or they're pretty accurate at predicting the minute. I got 59.56s - 35 y/o, not student, last night was a bad night I slept 6 or so hours, usually 8, don't know how that helps - barely any coffee, once or twice a week.


Err... How are you going to connect unique responses on your survey to the reddit replies? If you found a way to do the survey with the information you are asking in the reddit reply you could do some really fun regression analyses without risking people not filling out the reddit portion of the survey. Those analyses would be more fun if you changed "Are you a student?" to "How many years of education do you have?" Just some things to think about.


63.53s, 23, graduated, 9, 0


63.40s, 38 years, grad student. I slept about 7 hours last night and don't usually drink caffeine.


38.59s, 18, a student, 6 hours, no caffeine


61.30 33 Yes 7 4


I tried it 4 times. Best score was 59.84! (I cheated that time tho...) First was 72, second was 55 - these two I was keeping a beat, but not counting. Third was 76. Complete silence. Last was 59.84. I kept a beat and counted the beats. (And by keeping a beat, I mean clicking my tongue at the same rate as a grandfather clock - tick, tock, tick, tock...) Edit: forgot to answer the rest of the questions: * Age: 34 * Student: no * Hours of sleep last night: 7 I think? I woke up a bit groggy tho, so not the best sleep. * Caffeine intake: none. I occasionally have a 4oz cup of black tea as a treat, but none today.
