I've thought meaningful effect sizes are what people think a significant difference is, and that most scientists prefer that the general public remain deluded.
For the record, from the example, 2.5 inches would be considered a large effect size (as 1SD, from memory, it's yonks since I looked at stats) and something to get very excited about! but I wouldn't think someone who was 2.5 inches taller remarkably taller - maybe 6 inches taller is noticeably taller, but 2.5 inches is just taller enough for me to notice there actually is a difference!
It’s one SD of difference. There is 2SD too, 5 inches. But if you ask a woman about a male prospect and say “5’5” vs 5’8 (ish)” it’s the date vs no date threshold, i’m guessing. ;)
I'm really digging this perspective. Thanks for not only introducing me to this concept but also for spelling this out in detail.
I come from an engineering background and have always felt most comfortable when it was clear to everyone that we wanted to separate the numbers from how it felt. Writing out an equation that connects the two is brilliant for someone who has recently recognized the relationship liability that is presented when you ignore emotions (me!).

Not lame. Very creative!
I appreciate the feedback, consider sharing with people who need to understand what an effect size is in your life,

Looking forward to more good words.
Thank you so much for reading, and please feel free to share it with your world.
I know--but it's a goodie! More new stuff to come of course!
