Researching a specific technology?

[Ze]

I am trying to follow the tutorial, but I have been stucked ages on the next step "Uplift Pre-Sapients". To do that, I must research the Epigenetic Triggers technology. In the Stellaris wiki, I found that this technology belonged to the Society category, and I made sure that I had the prerequesite. However, every time a Society technology is finished, I end up with 3 random ones. So at the moment I just keep expanding with research vessels, build starbases and research for anomalies. Is there a way to get the technology I want? Can I trigger other tutorial points in the meantime?

The only way you can influence what research options you get is by the specialisation of the scientist. That wuold probably be genetics for waht you want.
You also need to have encountered a pre-sapient species.

The technologies you get are random. There are ways to make a specific technology more likely to show up, but it won't be guaranteed to appear.

In addition to requiring the Genome Mapping technology, you have to have encountered a pre-sapient species, and can not be a Fanatical Purifier. Its more likely to appear if you are some sort of Xenophile, and if the Society scientist has the Expert: Biology trait. Being any sort of Xenophobe will make it less likely to appear. And as a tier 2 technology, it requires you to have researched any 6 tier 1 Society technologies before it even has a chance of appearing.

1) check your own politics. for natives, there are choices if you can uplift them or not. sometimes it is deactivated by default. depending on your species.
2) if you are not playing ironman, you can safe and reload before end of reasearch nn that month. the time you reload research finish, you get new choices.

Thanks for the headsup

Epigenetic Triggers is Biology Tier 2 - so you want a research with a biology specialization. When he completes the prior tech he will give you a bonus on the roll for new techs that favors getting more Biology choices. It shouldn't be that hard to get.

There are empire conditions which can make it impossible to get that tech. I don't know whether the tutorial is smart enough to not give you the uplift mission if you have conditions which preclude it. Anyway, it's also perhaps possible that you got the mission, then enabled some policy that makes it impossible to get the tech.

You cannot get the tech if you have the Fanatic Purifiers civic.

And to get it one of the following 3 things must be true:

- You don't have Machine Intelligence authority, or
- You do have the Driven Assimilator civic, or
- You do have the Rogue Servitor civic.

So try to check all that, but it's confusing.

Finally, just to put some FUD on for icing, there used to be a "stuck tech" bug where the game would malfunction and just never give you the stuck tech. I don't know if that's been fixed in the last year, I haven't been playing. But it won't hurt to google up the instructions for the workaround and try those.

Hmm... I'm in year 2030 of my current game and I've not seen this tech either, even though I have a system with a presap on a planet in it. Did op ever get the research option?

Lol, nvm, the next time I completed a social tech I reloaded once and there it was...

Welcome to the worst part of PDX space games (all of them!), wich is the "Random tech progression/Random tech tree"... seriously? Randomness shouldnt exist in either of their space games (Yes, Sword of the stars 1 and 2 are from them as well...). There isnt even a mod for that! Thats how IMPOSIBLE it is to fix that right now!
