Join The Scientist Career And Make Groundbreaking Inventions!

The Sims 4: Get To Work features three amazing active careers, and Scientist Career is one of them! It’s time to brainstorm, make some groundbreaking discoveries, and be inventive. Being an active career, this one demands your full involvement, as you will have to work on completing daily tasks with your Sim, instead of just sending them off to work. There are 10 levels for you to conquer, and if you do everything well and rank up, you may even get a chance to encounter aliens and travel to Sixam. Sounds fun? Here is all you need to know about this career!

Ideal Mood, Compatible Traits, and Aspirations

The most useful mood you can have as a scientist in Sims 4 will be focused. No specific traits give notable boosts, but probably the most compatible ones are Genius, Cheerful, and Geek. The Genius trait is great for getting randomly focused. Cheerful Sims are more likely to feel happy, which can help battle negative moodlets they can get when using serums and inventions, and help them perform better. The Geek personality trait ties well with the career theme but won’t give you any special extra advantages. The Curator aspiration is probably the most useful and compatible since your Sim will need to do a lot of collecting as they progress in their Scientist career.

What It’s Like To Work At The Lab?

Scientist Career 1

As a scientist, your Sim will work with fellow scientists at the Science Lab. All your daily tasks will be listed in the career menu, and shown in the upper left corner of your screen, where you can track your progress. This will change every workday once you arrive at the lab. Besides creating key inventions and serums required for promotion (listed in the table below), this can also include simple activities, such as practicing analysis, socializing with coworkers, upgrading the Sim-Ray, or even watering plants in your lab! Some take just minutes, while others, such as making serums, take more time to accomplish.

When you arrive at work, the game will notify you about the main theme of your work day. You may have aliens infiltrate the lab, have daily experimentation days, or collect days, when you can focus on digging for collectibles needed for making serums and inventions.

How To Have Scientific Breakthroughs?

Scientist Career 2

Having breakthroughs is essential for promotion on all levels. Look at these as random eureka moments. Your Sim can get them while browsing Simpedia, running on a treadmill, using a microscope, experimenting at the chemistry lab, having a thoughtful shower, pondering chess moves, or reading a book – just to name some. Scientists will need 2 extra breakthroughs every time they level up. Every interaction with an object that can provide a breakthrough will show with a lightbulb symbol. And, if your Sim gets a breakthrough, they will also get a light bulb above their head.

Serums And Inventions

Besides breakthroughs, to level up your Sim will also need to make serums and inventions. We will list the ingredients needed for all serums and inventions below, but if in doubt, you can check the ingredients in your Sim’s notebook. While you will need to create both serums and inventions at the first 6 levels, your focus will be entirely on making serums on the next levels.

Once your Sim becomes the Laboratory Leader at level 7, they will unlock the ability to give orders to coworkers in the lab, which is a great time-saver. You can order them to analyze crystals, experiment, invent, work on the rocket, or even visit aliens! Now, onto making serums and inventions!


Scientist Career 3

To reach the top of the career, your Sim will need to make 15 different serums, and most of those have a decent value. You’ll need plants to make them, so buy seed packets and plant plants at the lab or at home as early as you can. Once you have all the ingredients just use the chemistry lab.

Your Sim will need to test serums, though. They can do this themselves, or give serums to coworkers to try via Test Serum social interaction, which is a better option since they can give some negative moodlets if tainted. Once you make a serum, if you are past level 5, you can also use the cloning machine to duplicate them, which requires zero materials.

Scientist Career 4

All inventions are made with the Invention Constructor at the lab. There are 6 of them, and they all have a special effect. SimRay, Satelite Dish, Cloning Machine, and the Electroflux Wormhole Generator can also be upgraded on higher levels to unlock additional functions. To upgrade them, just drag them to Invention Constructor!

You will need to collect metals and crystals to construct some of these devices, and you can dig for them near your lab, or ask your coworkers if they have some. To get elements, follow this guide. Here are all of the inventions listed, along with the materials needed for their construction and the effect they have on Sims:

Wrapping It Up!

The Scientist Career is one of the game’s most fun and lucrative careers. Besides the salary, Sims can also earn decent amounts from transforming objects with Sim-Ray, copying objects, or even selling collectibles they don’t need. Besides completing daily tasks, they will also get to interact with aliens, especially on higher levels, which adds extra sauce to this career!
