We don't fully understand why some people develop severe allergic reactions to foods that are harmless to most others.

open Global / Unspecified, Global

Food allergies have been rising for reasons researchers still can't fully explain, and existing treatments mostly manage symptoms after exposure rather than removing the risk entirely. A true prevention or cure remains elusive.

We haven't resolved whether it's possible to justify treating certain forms of self-deception as harmless or even beneficial.

open Global / Unspecified, Global

Mild self-deception can sometimes protect wellbeing or motivation, but it's unclear whether this ever fully escapes the broader ethical concern around avoiding false beliefs. This unresolved tension touches on both personal psychology and the ethics of belief.

We haven't resolved whether an action can be morally wrong even if it harms no one.

open Global / Unspecified, Global

Some argue that harmless private actions, like certain personal choices, shouldn't be subject to moral judgment at all, while others believe morality extends beyond direct harm to virtue and character. This unresolved question shapes debates over the proper scope of ethics.

We can't yet build home security camera systems that reliably distinguish between genuine threats and harmless everyday movement.

open Global / Unspecified, Global

Many home security systems still generate frequent false alerts from pets, shadows, or weather, reducing their practical reliability for identifying genuine security concerns. Improving this accuracy without expensive hardware remains unresolved.
