I assume informal. Are there any cases when you would use formal, perhaps to
be sarcastic? And general, is informal or formal language used more in life (I
mean for the average person - is it around 50-50? Or lopsided to one
direction?)

question
formality
Do Japanese people use formal or informal language for internal monologues?
Hard to say... until age 18 or so you'll use a lot of informal language
because you have a lot of peers around (though if you are in a sports club the
situation might be different). Depending on where you work, that can change a
lot when you get a job and you have hardly any peers.

When there is an age difference, even if you are friends, you often keep using
formal language, so you also use it for very close relationships.

If I had to guess 80% informal and 20% formal? I don't think people think in
formal language though I have no proof.

I thought your question was a bit vague. Do you mean to ask if Japanese people
use 敬語/polite form when talking _among_ themselves? Or are you asking if they
think and talk _to_ themselves in 敬語?

Most of us learners learn 敬語, the formal style, first. That is usually the
first style of speech/writing we learn in our Japanese class. But for native
speakers it is different. Japanese kids use ため口/informal language growing up,
with parents and siblings. I seem to recall several newer Japanese
textbooks/online courses claiming that "teaching language learners です・ます first
is unnatural", citing as an important reason something to the effect that "the
traditional teaching methods have failed to accustom language learners to ため口,
but in reality ため口 is widely used by native Japanese speakers."

Most Japanese kids start to correctly and profeciently use です・ます（敬体{けいたい}）in
小３、小４ (3rd and 4th grade). (Heard this from my students. Some online sources
also seem to suggest age 10 is something of a watershed in terms of formal
language use. [「子供が敬語を正しく使い分けられるのは10歳頃からです。」](https://sengakuhisai.com/keigo-
nansai-kara/)) Enter 敬語（丁寧語・尊敬語・謙譲語）around 小５ (5th grade). By the time
Japanese kids enter middle school, they are fully adept at 敬語/formal style. I
have taught and tutored a lot of Japanese students from 中１ through 高３ (middle
and high school) English and math, and they interact with each other in
です・ます（敬語） when they are not yet on familiar terms. This is also the case in 塾
(cram school) where students don't necessarily get to know one another very
well or make friends. Of course at school it is a different story. A lot of
middle/high school students use ため口 at school with peers and people younger
than them. In the workplace 敬語 becomes the predominant style of speech.

@naruto's correction and supplemental information:

> Kindergarteners do understand and use basic ですます style. Folktales like

In terms of 独り{ひとり}言{ごと}, when they talk to themselves, most Japanese people
use ため/informal language, of course.

This question is interesting, but hard to answer with confidence, because you
don't talk about what you talk to yourself to others very often?

When one talks to oneself, especially in inner speech, I'd assume 敬語 doesn't
appear in most cases. This is because you don't have to be formal to yourself,
and because talking to oneself is more akin to thinking rather than
communication. Using 敬語-style is essentially a matter of relationships, which
is irrelevant to some degree in thinking. (Playful uses 敬語 can be seen,
though.)

A supportive, albeit indirect, observation could be sought in dramas and anime
(and manga): when a character's thoughts are inserted verbally (soliloquies),
I feel that 敬語 is less likely to be used even in those polite characters. I
might be proven to be wrong.

On the other hand, I do have occasions where I strongly tend to use 敬語 in
internal monologue or talking aloud to myself. It is when I talk to myself as
another me. For example, I often talk to myself at work in order to organise
my thoughts: it's kind of consulting another professional, which happens to be
me myself[*1], about the problems at hand. In such cases, my speech is similar
to those I make to my colleagues.

I consider myself to be highly talkative-to-onself, so this may or may not
happen to many people. But I think it's true that which style you choose when
you talk to yourself depends on the distance between you (the talker) and
yourself (the listener).
