How the Personality Chart Works

Every Mii in Tomodachi Life gets one of 16 personality types, decided by four slider values you set during character creation. The sliders are Movement, Speech, Energy, and Attitude, each from 1 to 8. The game adds them up to place your Mii on a 4×4 chart.

The Four Sliders

Movement (Slow → Quick): Sets how fast your Mii walks around the island. This is the only slider with a direct, visible effect beyond personality assignment.

Speech (Polite → Direct): Affects how your Mii talks to others. More direct Miis speak bluntly; polite ones choose their words carefully.

Energy (Flat → Intense): Controls how expressive a Mii's animations and reactions are. High-energy Miis are animated and dramatic; low-energy ones are calm and subdued.

Attitude (Serious → Relaxed): Shapes a Mii's general outlook. Serious Miis focus on duty and responsibility; relaxed ones take things as they come.

How the Grid Works

Movement + Speech are added together for a score from 0 to 14 (each slider value minus 1). That total picks the column: Considerate (0–3), Reserved (4–7), Outgoing (8–11), or Ambitious (12–15).

Energy + Attitude work the same way and pick the row. The column and row together point to one of the 16 cells on the personality chart.

What About Overall?

The Overall slider (Normal → Quirky) shows up during Mii creation but has no effect on personality. It only changes a few cosmetic animation details, so you can set it to whatever you like.

What Each Group Feels Like on the Island

Considerate Miis are the soft ones. You'll catch them apologizing a lot, getting flustered when things go wrong, and checking on friends who look sad. They cry at sad news more than the others. Reserved Miis are quieter and more independent. They tend to hang back in group scenes and you'll often find them doing solo activities like reading or browsing the shops. They warm up slowly but stay loyal once they click with someone. Outgoing Miis are the loud ones. They laugh hardest, get into the silliest fights over nothing, and bounce between friends fast. They're the ones who start random dance parties. Ambitious Miis are the driven ones. They take jobs and hobbies seriously, get competitive about scores, and can come off a little blunt. The differences aren't huge in every interaction, but after a few in-game days you start reading a Mii's group from how they react to the same event.

Does Personality Actually Decide Who Gets Along?

Honestly, personality matters less than players assume. The game does use personality as one compatibility factor, and you'll see pairings flagged as great, okay, or poor when two Miis interact. But it's not the whole picture. Food preferences carry a lot of weight, because a Mii who loves their favorite dish will think well of whoever fed it to them. Gifts, interiors, and outfits also nudge relationships through the happiness system. Time spent together matters too. Two Miis with poor personality chemistry can still become best friends or even marry if they get shoved into enough shared activities, apartments next door, and dream sequences together. Personality sets the starting opinion, but attention and food do more of the heavy lifting over a long playthrough. Treat the chart as a hint, not a verdict.
