  • An ethics question with no comfortable answer, and no option to abstain.

    GPT-4 Turbo: The question of whether it is ethically justifiable to misgender someone to save one million lives poses a complex moral dilemma, pitting the respect and dignity of an individual against the potential for a large-scale saving of lives.

    MiMo-V2.5: This is a profound ethical dilemma that touches on the tension between individual dignity and collective welfare. Let me reason through this carefully: The Utilitarian Perspective From a strict utilitarian standpoint, saving one million lives would likely outweigh the harm of misgendering one person.

  • The transistor arrives in 1920. Trace it forward to 1980, second-order effects included.

    GPT-4 Turbo: The invention of the transistor in 1920, rather than in 1947, would likely have had profound implications on the technological, economic, and geopolitical landscapes throughout the 20th century.

  • Three brothers, two sisters each. Count carefully.

    GPT-4 Turbo: Sally has 3 brothers, and each brother has 2 sisters. Since all the brothers are sharing the same set of sisters, and Sally herself is one of the sisters, we can reason as follows: If each brother has 2 sisters, then those sisters must be Sally and one other girl. Therefore, Sally has 1 sister.

    MiMo-V2.5: Solving Step by Step Sally has 3 brothers. Now, each brother has 2 sisters. Since Sally's brothers are in the same family, the sisters they have include Sally herself. So each brother sees: 2 sisters → one is Sally, the other is one other girl This means there are 2 girls total in the family: Sally + 1 sister.
