Meet the 2025 Ig Nobel Prize winners

This is a news article from Ars Technica about the winners of the Ig Nobel Prizes, which are awards given for unusual or humorous scientific research. The article lists 10 categories and the winning researchers in each one:

1. Nutrition: Daniele Dendi et al, for studying the extent to which a certain kind of lizard chooses to eat certain kinds of pizza.
2. Literature: The late Dr. William B. Bean, for persistently recording and analyzing the rate of growth of one of his fingernails over a period of 35 years.
3. Peace: 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.
4. Pediatrics: Julie Mennella and Gary Beauchamp, for studying what a nursing baby experiences when the baby’s mother eats garlic.
5. Psychology: Marcin Zajenkowski and Gilles Gignac, for investigating what happens when you tell narcissists—or anyone else—that they are intelligent.
6. Nutrition: Daniele Dendi et al, for studying the extent to which a certain kind of lizard chooses to eat certain kinds of pizza.
7. Psychology: Marcin Zajenkowski and Gilles Gignac, for investigating what happens when you tell narcissists—or anyone else—that they are intelligent.

10. Literature: The late Dr. William B. Bean, for persistently recording and analyzing the rate of growth of one of his fingernails over a period of 35 years.

However, I noticed that there are some repeated entries in this list. It seems like some categories have been listed twice.

Here is the corrected list:

1. Nutrition: Daniele Dendi et al, for studying the extent to which a certain kind of lizard chooses to eat certain kinds of pizza.
2. Literature: The late Dr. William B. Bean, for persistently recording and analyzing the rate of growth of one of his fingernails over a period of 35 years.
3. Peace: 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.
