Heres the thing you gotta understand about statistics. 

“Increases your chances by 80%” does not mean “there is now an 80% chance”. 

If your chances were previously 10%, your chances are now 18%, not 90%. 

if your chances were roughly 1%, they’re now just slightly less than 2%. 

thats how that works. 

Wow I don’t understand math at all

‘if you have a baby after 35, the chance of deformities goes up by 100%’ is a line I hear alot.

It goes up from .5% to 1%

I think my brain just stopped working

100% is just another way of saying twice more likely. So 100% more basically means multiply the number you do have by 2.

It goes up by that percentage of the previous number.

For example, let’s say your chance was 10%. It just went up by 10%.

10 is a.. factor? Idk it’s related to 100. So 10% of 10 is 1 (10% of 100 is 10, but I at least think that’s obvious since % is based on 100)

So your chance is now 10% + 1% which is 11%. Or 10% + (10% of 10%), which is 11.
