That's it for this year! Congratulations to all the prize winners. More here:

Very useful stuff. I now know I was right about my fingernails growing slower as I get older. We do need some replications to make sure of it and should expand the study to include toenails.
 
Yet I have been assured that using non-stick pans will give me Teflon Turbocancer from ingesting trace amounts of it with the food. Are you saying WebMD lied to me?!
 
As I’m sure everybody knows, the saddest thing about all these”studies” is that they, somehow, received (usually) government funding. As someone who spent years putting together government funding proposals, I feel ill.
 
Mrs Wobs found a PhD today that should there. It was basically that a book doesn't get the recognition it should (while another does get it), and so they wrote a PhD on it.

You don't think discovering the perfect recipe for Cacio e Pepe is a worthwhile endeavour?

I was kind of hoping they'd give on to RFKJr in Medicine, for improving the business prospects of doctors and hospitals by making America sicker.
They're not anti-Nobel prizes. All of the studies recognised were real science, with real outcomes.

(Tl;dr: Growth slows as you age)
I feel like mine grow faster, but that may just be a side effect of the fact that time seems to pass faster as I age. When I was a little kid, a year felt like a very long time. Now that I'm middle-aged the years (and months and weeks) seem to pass in no time.
Biology Prize [Japan]
Tomoki Kojima, Kazato Oishi, Yasushi Matsubara, Yuki Uchiyama, Yoshihiko Fukushima, Naoto Aoki, Say Sato, Tatsuaki Masuda, Junichi Ueda, Hiroyuki Hirooka, and Katsutoshi Kino, for their experiments to learn whether cows painted with zebra-like striping can avoid being bitten by flies.

(Tl;dr: It works)
I've heard about this with respect to zebras. For some reason, their stripes seem to protect them from biting insects to some extent.
If it's paint on the cows though, you have ask whether the smell of paint is an insect repellent.

Chemistry Prize [USA, Israel]
Rotem Naftalovich, Daniel Naftalovich, and Frank Greenway, for experiments to test whether eating Teflon [a form of plastic more formally called “polytetrafluoroethylene”] is a good way to increase food volume and hence satiety without increasing calorie content.

(Tl;dr: It is)
But is it safe? These are "forever chemicals" we hear so much about lately.

Peace Prize [The Netherlands, UK, Germany]
Fritz Renner, Inge Kersbergen, Matt Field, and Jessica Werthmann, for showing that drinking alcohol sometimes improves a person’s ability to speak in a foreign language.

(Tl;dr: aka Dutch Courage aka it's good to get drunk with Germans)
Not surprised. People who are usually shy or self-conscious when sober lose their inhibition to speak. And that explains most of it.
You have to stop being afraid that you'll say something dumb or that people will judge you for what you say.
 
As I’m sure everybody knows, the saddest thing about all these”studies” is that they, somehow, received (usually) government funding. As someone who spent years putting together government funding proposals, I feel ill.
You could try wording them differently. Creative writing! Make a serious proposal sound like some wankery, and see if that gets it over the line.

That's it for this year! Congratulations to all the prize winners. More here:
My favorite: the zebra thing. Hilarious without being gross --- except for the cows picked to experiment on, I guess. As well as cool, in that it should turn out to work. (Going by your post, didn't click on further.)

Next favorite is the apparently randomly labeled literature prize for the nail guy.
 
I was kind of hoping they'd give on to RFKJr in Medicine, for improving the business prospects of doctors and hospitals by making America sicker.
Absolutely!

eta: And the Peace should, even more absolutely, have gone to Trump.

etaa: No, scratch that. Agreed, like @arthwollipot points out, these are not anti-Nobels, but actual science, each one of them. So no, to both.

On the other hand, the labeling is weird. Why Literature for that one? Why Peace for the drink thing?

*leaves off compulsively overthinking this thing!*

They might have done 30 years ago, for example they gave Dan Quayle* an award for "demonstrating, better than anyone else, the need for science education."


*Cited as "consumer of time and occupier of space".
 
The mission statement of the Ig Nobel prizes is "...to make people LAUGH, then THINK. We hope to spur people’s curiosity, and to raise the question: How do you decide what’s important and what’s not, and what’s real and what’s not — in science and everywhere else?" (link)

It is not to call out bad players but to celebrate good, if quirky, ones.

These days, yes. But, for example, Benveniste was a double laureate (1991 and 1998).
