Which trait has the least impact?

Bookworm is by far the most useless trait I have ever seen; I don't remember it ever doing practically anything except being able to analyse books, and that's not even that interesting.

I've played quite a few Cheerful Sims. Maybe it's just me, but I think their Fun goes down slower, so they get Tense less.

I agree with the cheerful trait. I don't really see a difference with my sims having it or not. same goes with the bookworm trait because as long as you have a book shelf near by most sims would opt to grab a book, sit down and read for some reason.

Clumsy

A lot. I do love have the sims tend to develop their knowledge based on the player but the traits. It feels that they are undeveloped. At the pre-release of The Sims 4 we are been told that because of the traits, the way we play each sim will be different compared to each other.but really they are not powerful enough to to change the way we play each sim. They should change gameplay when we choose a specific trait.

Example of the traits that aren't powerful enough to change the way we play and just there. (Actually these felt more of a moodlet to me)
Good - Aside from being able to donate from charity, and discuss world piece, what is the game changing attribute that this trait have?
Outgoing - Decays social need faster. So what's next? Any game changing?
Hot Headed - They got angry when they are been thrown by mischief. Other than that they are one of the happiest sim of the world.
Genius - They get focused then there is nothing left. I can make any sim focused already without even needing that moodlet. They don't act smart really.
Self Assured - Trait to only make them confident. Where is the challenge? The game changing attribute where did it go?

Those are just some. They have no game changing attribute which is why we tend to play the game the same. The AI learn from the player. Its like they have no character and you have to create their character by playing them. However since we want to play in a specific way the result are sims having the same reactions. Traits are there to stop us making our sims to be the same. But since they are powerless then its nothing. A in-depth example is this

http://sims.wikia.com/wiki/Genius_(The_Sims_3)

The difference is massive.

Other thing is moodlet should be based on traits. Example a hot headed sim should get angry if the place is dirty compared to other sims. If a sim is a slob and cherful, he should be happy.

I'd say the Cheerful or Good traits would have the least impact on the sim

I have to disagree with you on Hot Headed and Good. Hot Headed sims get random angry moodlets that last 4 hours which does have an effect on gameplay. Good isn't as powerful as Hot Headed imo, but it does affect certain things, like being sad around Evil Sims and happy around other sims in good moods. I fully agree on Genius though.

a lot of them really:

non-committal is not powerful enough, and I've yet to see the tense moodlet. They get happy like anyone else when they start a new relationship... I'm non-committal, I would be less happy and I would get tense the day after thinking something like "why did I get myself into this?!"

hates children is pratically useless, they are happy like anyone else around their own children.

evil is a little more powerful, but I could befriend evil sims just fine.

I got into steamy conversations with unflirty sims in the same ammount of time of any other sims while playing the serial romantic aspiration.

dog/cat lover.... I wish they were reward traits in fact, they are a waste of space as cas traits.

I only think about traits when I have to assign them.
They are pretty forgettable.

Except for the Jealousy trait. :D

Music Lover.
Honestly, most of the traits in CAS don't really have an impact, the sims end up acting the same more or less.
