  2. Increase: It can increase based on decisions you make as you develop your country.
  3. Universities: Building and fully staffing universities is an effective way to boost your Innovation. Universities play a primary role in increasing your Innovation intake. You can qualify people through universities to staff the buildings you construct.
  4. Literacy Level: Your nation’s literacy level affects how effectively you can utilize Innovation to research selected technologies. Even with top-tier universities, low education levels among your population can hinder successful implementation of new knowledge.
  5. Primary School System: Maintaining a strong primary school system is crucial, alongside advanced universities, especially for nations aiming for global growth and innovation leadership.
  6. Research Time: If your Innovation hasn’t sufficiently advanced, research may take a long time. In such cases, consider exploring alternative, less expensive technologies until your Innovation rate justifies focusing on specific research goals.

One of the three technology trees in Victoria 3 will always be investigated by Technology Spread. Here’s how it works:

  1. Random Technology Focus: One of the three technology trees is selected for Technology Spread research. These technologies are chosen randomly from a list of those studied by other nations but not yet by your nation.
  2. Advancement Rate: The rate of advancement toward these selected technologies is also randomized, primarily influenced by your nation’s Innovation and literacy levels.
  3. Impact of Literacy: Literacy within your population significantly affects how quickly technology spreads. Any excess Innovation beyond the Literacy cap is directed toward speeding up the spread of new technologies.
  4. Educational System: Having universities that surpass your educational system’s capacity can help you catch up with the world but won’t allow you to surpass other nations.
  5. Freedom of Speech Laws: Your nation’s freedom of speech laws affect technology diffusion. Increased censorship grants more control but hinders the absorption of new information, which may or may not align with your goals.
  6. Education and Foreign Ideas: A more educated population is more open to foreign ideas, some of which may not align with your agenda. Exerting governmental control over what your population can discuss can help maintain focus on specific concepts you want them to be aware of.
