Did the study say anything about the moisture content of water or the color of the sky?

Imagine two people having an online discussion about model railroads.

With pseudonyms:
A :Bruce Wayne, 35, Gotham City
B: Master Yoda, 900, Dagobah

Without pseudonyms:
A: Lisa Johnson, Nickname: Bruce, he/him, 14, Canada
