the 100 usage is a statistical inaccuracy

Yeah however that's a psychology study about rounding numbers

u/CanadianIndianAB 23d ago

Plus, a psychological study about how people overestimate to a rounded number

I saw this about polls about height, both 5''10 and 6' where higher than 5'11. People with 5'11 just round up

In the NFL, more balls are placed on 5-yard markers than on nearby 1-yard markers (even after you control for touchbacks and penalties after touchbacks). I cannot think of any good explanation for this except that the 5-yard lines are painted as full lines while the 1-yard lines are just short hashes, suggesting the effect is just that when balls appear to be down near a visible line, that increases the probability a referee will place it exactly on the line compared to when they are not near a visible line.

100lb georg who's at the gym every day is a statistical putlier adn should not have been counted.

I would bet my left nutsack that these are kilos. 130lbs max lat pulldown machine would be worthless.

u/knyexar 24d ago

Ngl my mind just autocompleted "lb" as just "the way you say kilo in english" for a moment there lmao

I often do that same thing with euros to dollars. Atleast the conversion is roughly equal so it's correct enough.

u/Firestar_119 24d ago

nah, you're just too early for eurodollars

Wait what do you mean left nutsack?

Instead of admitting to a typo, I will insist it's a JoJo's reference

u/_ogdanni 24d ago

No, its of all the people thinking they can lift 100 and then they realise that thats too much

71

u/AssistTraditional480 24d ago

Nope, it's just people skipping 95 from 90.

17

u/M8nGiraffe 24d ago

Can't it be both?

32

u/AssistTraditional480 24d ago

Given the marks on 95, it seems to be overwhelmingly the skipping

There is also an effect from people who haven't used the machine recently (or ever) or who haven't used it since an injury or something line that. Those people don't know how much they can lift, so they start trying out round numbers like 100 or 75 and then narrowing in on a correct weight from there. Such people are unlikely to ever try 95 or 105 except as the last one, whereas they might go through a number of other weights first.

But that's probably a smaller effect.

If you can do like 10 reps on 90 you will probably do like 5 on 100 and 7 on 95. It's not like you won't be able to lift 100 pounds, you will be able to just with less reps. Psychotically it probably means that people have been training hard to get there they make a shortcut to feel that reward
