how do i lower inhibitions quicker? or is it a slow-paced game?
For individual persons, drugs (I think slut maker and corruptor both affect inhibition, but I think the former is faster) and hypnosis are fast ways to lower inhibition.
Drugs are generally very fast ways to affect stats. You can use them as an item on someone. Newer versions really make it tough to apply drugs as an item to a person who is awake. If they see you doing it and slap it out of your hand, their loyalty goes down and I think you also take a rep hit. If you can find the person asleep, you're more likely to be able to use a drug as an item on them, and I don't think they're able to detect you doing it.
For people who have high loyalty, you can trade drugs to them and they'll use one on a daily basis until they run out. You might not be able to give them more than one at a time, though. Not totally sure what determines that.
For the general population, there is a chemistry lab event that, I think, can lower inhibition if it works right. It's kinda tough to pull off, doesn't fire often (I think it's once a week at most, checked when you enter the chemistry lab's back room), and I forget if you can pick which stats get changed.
You can, if you are carrying drugs, sometimes spike the cafeteria food with them. Last time I remember doing this I think I was actually there at the end of the lunch period, but try hanging out in the cafeteria skipping in 10 minute increments through the lunch hour. Dunno if this affects all students and faculty or just those that actually visit or have visited the cafeteria.
Hypnosis can be used to directly lower inhibition, but it doesn't work reliably on individuals even with 100 hypnosis skill. If the skill check fails, the person notices you doing something weird and you get a rep hit and I think a loyalty hit for that person. Also, you have to be alone in the room with the person in order to change their stats. However, if you hypnotize someone when others are around you can order them to follow you to a private area and then re-hypnotize them. I'm pretty sure you can't maximize or minimize a person's stats with hypnosis, either.
The mind control device, if you find it, I think lets you do everything that you can do with hypnosis without the chance of failure. You need to spend money on batteries, though, and have to get a person alone before you can use it at all. I also don't think you can buy it back if you sold it to the private eye, but I'm not sure about that one.
There are hypnosis events for affecting an entire class at once, but I think only some of the options work on inhibition.
Lastly, how little clothing you are wearing around others has a chance of affecting their inhibition. You really have to play around with this system to see how little clothing you can get away with before you start to suffer reputation damage because you're too scantily clad. A principal who is more attractive can apparently get away with being less dressed than one who is less attractive. Also, the only cue that you are successfully influencing inhibition is an audio cue, but if you're losing reputation you thankfully get a message about it. It can be kinda weird to get a rep hit from wearing a short sleeved shirt that shows some cleavage, but the system is very numerical and it only takes one high-inhibition dork seeing you to trigger a disapproval message. Someone did a pretty good job explaining it in the in-game writeup in the clothing closet.
