Let me know your thoughts on this trend? Is there any research I can reference to learn more?
Not seeing that in the real world. However, as the IT world is male dominated and, for whatever reason, IT people (especially coders) seem to prefer it, it would appear that men prefer darkmode.
Personally, I hate it (tho my partner, prefers it on her phone). I find it harder to read unless it's done really well, and having a dark screen greatly increases background reflections which further make reading the screen more difficult. Generally, I consider it is a terrible UX.
Darkmode was devised by coders working in darkened rooms, often at night. In that situation it's logical. However, in brightly lit offices or outside, it makes no sense whatsoever.
Very intersting question. I've always felt like men have a more favourable disposition to dark mode than women but it's purely annecdotal and subjective so would be interested to know if there's any data to back it up.
