Use the 'research' cheat option at the bottom of the screen. Click on a trait to research it instantly. Click on the trait to level it up, reducing side effects. Get an autoclicker for high capacity design, as you have to click 200 times to get it to 0% side effects.
There's also a 'cheat' cheat option at the bottom of the screen.
Ya ... I go the route of editing the <extractedFolder>/renpy/common/console.rpy to change config.console = True
Then shift O
type long and return
dir() and dir(some variable) is your friend
Then screw the skill boundaries - game as of yet doesn't reset you to a maximum. (please don't change this)
mc.research_skill=50000
[rinse and repeat for the other skills][look to first page for link to other console commands]
Research once to get it ... then research again for 0%. There's only a few annoying ones that still whittle away at 1-2% with this so you have to repeat 3 or 4 times. [For Nora's initial quests this means just research it once and report back to her without doing anything meaningful with her serum]
Much better than the autoclick.
Only downside is when employees want you to teach them and they go from 5 research_skill to 10000 research_skill and start sucking your money dry. (the_person.research_skill=8) can't afford them employees to be too smart.
Aside from that I cheat the Nora Reasearch Surveys once she starts asking for them (from post in orig game forum)

After x+ versions of restarting the game sooo can't be bothered to play it legitimately ever again.
