The main technology interface

Technology represents the discovery, improvement, and implementation of new tools, techniques, and customs that give a wide variety of powerful bonuses across every field. Technologically advanced nations will field a more effective military, make more efficient use of their pops and resources, and be able to create a more stable and loyal realm, while those that fall behind will find it increasingly difficult to keep up with their peers. All technologies fall into one of four fields - martial, civic, oratory and religious - and can be divided between generic advances that gain progress from generation of research points by nobles and citizens and more specific inventions that can be bought using gold. The main technology interface can be accessed though the Technology button in the top bar.

Advances

Advances represent the general level of knowledge and technology that the country has reached. They provide a baseline level of modifiers from increased technology and each advance unlocks 3 inventions to be added to the pool (occasionally more if the country has access to culture or government-specific technologies). There is no cap in the maximum level of advances that can be achieved, though after level 20 advances will stop unlocking new inventions and will only provide their base modifiers. Advances are slowly researched over time based on the amount of research points that a country produces in proportion to its integrated culture population, subject to many different modifiers that can further increase or decrease the speed at which research progress is accumulated.

Research Points

Research points represent the contribution of pops towards the technological and intellectual advancement of the country, and are summed up over every pop in every owned territory every month to get the total research points for the state. Research points are generated exclusively by nobles and citizens, who produce a base output of 0.5 and 0.2 research points, respectively, each month at 100% happiness. Therefore, research point production is affected by noble output and citizen output as well as research point modifiers, and is also heavily dependent on the proportion and happiness of nobles and citizens in the country. This means that increasing noble ratio and citizen ratio directly through laws and libraries and courts of law or indirectly by building more and larger cities (as nobles and citizens do not exist in appreciable numbers in settlements) are also an effective longer-term solution towards increasing research point production. Large cities and metropolises are usually the largest source of research points in the middle to late game, as the stacking effects of libraries, courts of law, and academies means that they usually have both the highest proportion of nobles and citizens and the highest research point production per noble/citizen, though population capacity means that larger empires will still need a significant number of cities to produce enough research.

Research Efficiency

Research efficiency is the ratio of research points produced per year to integrated culture population and the main component of the actual research progress each month, meaning that larger countries generally need higher research point generation in order to keep up with research. It is calculated according to the following formula:

[math]\displaystyle{ \text{Research efficiency}=\frac{\text{Research Points}\cdot 12}{\text{Integrated Culture Population}}\cdot 100% }[/math]

Generally, it is desirable to keep research efficiency at at least 80% in order to research advances at a reasonable pace. Research efficiency cannot go higher than 300%, though it can still be useful to try to push the research points to population ratio higher in order to provide a buffer when enslaving pops or conquering new territory. Small, highly urbanized city-states will generally have a much higher research efficiency than sprawling empires with many rural pops, though it is possible to have a high research efficiency even with the largest empires so long as the major cities are sufficiently large and research-focused, of which growth through enslavement, migration, and continued urbanization will typically be needed to keep up.

As the denominator of research efficiency is based on the integrated culture population, not the total population, it is also possible to get high research efficiency by keeping a relatively small core of integrated culture pops compared to the empire's total output - especially useful is conquering foreign areas with significant numbers of nobles and citizens, as they will produce research points but not count against the denominator for research efficiency. However, the lower happiness of unintegrated culture pops, and particularly those of the higher classes that produce research, generally means that more care has to be taken to ensure their happiness and keep unrest under control compared to integrating them.

Monthly Research

Monthly research is the base value of research progress for all four fields and is obtained by dividing research efficiency by 240, corresponding to a base time of 240 months (20 years) for each advance. The research efficiency cap at 300% means that the highest possible base monthly research is 1.25%.

Research Progress

Research progress is the actual monthly progress in each field of advances. The base value is the monthly research, which is then modified by the field-specific research speed modifier. The technology speed modifier affects the research speed in all fields, while the field-specific technology modifiers ( military tech investment, civic tech investment, oratory tech investment, and religious tech investment) are applied only to the research speed of one specific field. Modifiers to research speed can come from various deity bonuses and omens, country heritages, trade goods, and event/mission modifiers, but the main component of research speed for each field will typically be the attribute of the field's researcher corresponding to the field. The behind/ahead of time modifier is applied multiplicatively after all the other modifiers, and gives a -0.50% malus for each year ahead and +0.50% bonus for each year behind the country is compared to the benchmark of 1 advance every 20 years after the start of the game.

An advance will be researched once the total research progress for that field reaches 100%, with any overflow carried over for the next advance. The progress and effects (including unlocked inventions) of the next advance in each field can be viewed in the tooltip of the corresponding progress bar.

Researchers

Each technology field can have one researcher assigned to it, who leads the research efforts in that field and has a significant influence on how quickly advances in that field progress, giving a +10% research speed boost for each attribute point corresponding to the field ( martial for military advances, finesse for civic advances, charisma for oratory advances, and zeal for religious advances). Like all other jobs and offices, holding the researcher position counts towards prominence, family prestige, power base, and the number of positions that a major family expects to hold.

Fields

The modifiers for a single level of advances in each field are listed below. Each level provides an additional modifier on top of the previous ones already accumulated.

Martial Advances

• +0.07 Morale of Armies
• +0.07 Morale of Navies
• +5% Army Maintenance Cost
• +5% Navy Maintenance Cost

Civic Advances

• +2% Population Capacity
• +2.5% National Commerce Income

Oratory Advances

• +2% Country Civilization Value

Religious Advances

• +2.5% Omen Power

Starting advances level

Each country starts with a predetermined level of technological advances, usually determined by their culture and civilization level.

The following countries/cultures start with all advances at level 2:

• Italic culture group (except Ligurian, Venetic, and Rhaetian)
• Hellenistic culture group ( 派俄尼亚,  卡帕多基亚,  帕提亚, and  特拉布宗)
• Punic and Phoenician culture (except  具姆奈西亚)
• Assyrian culture
• Median culture
• Tamil culture (if coastal)
• Magadhi, Shauraseni, Gandhari, Avanti, and Lankan culture
•  阿普利亚

The following countries/cultures start with all advances at level 1:

• Bactrian culture group
• Meroitic culture group (except  玻拉斯)
• Aksumite culture group
• Ligurian culture (except  俄克叙比亚)
• Aramaic culture
• Hebrew culture
• Colchian, and Ibero culture
• Armenian culture
• Tamil culture (if inland)
•  卡帕多基亚
•  帕提亚
•  迦陵伽
•  罗絺迦

All other countries start with no advances (level 0).

Inventions

Inventions represent specific technologies or practices that can be adopted by the state in order to get a specific bonus. Every invention is associated with a specific level and field of advances that needs to be reached before the invention is unlocked, typically with every advance unlocking 3 inventions (occasionally more when culture-specific inventions are unlocked). There are a total of 279 inventions spread across the four fields (251 available to all countries, 2 available depending on country rank, 3 government type-specific, and 11 country/culture-specific), with the last inventions being unlocked after reaching level 20 of each advance; higher levels of technology after that do not unlock any further inventions.

Each field has a pool of up to 3 inventions that can be adopted at any given time, with the most recently unlocked inventions always chosen first. Inventions can be adopted at a base cost of 0.15 gold per pop in each of the country's owned territories, which means that larger empires need to pay significantly more to adopt an invention. This cost can be adjusted by the Invention Cost modifier, currently possible only from a special event modifier. Not adopting inventions has no penalty other than not having access to the bonus and does not prevent further advances from being researched or new inventions from being unlocked and added to the pool, but as the newest inventions are always chosen first from the pool it will require purchasing a significant number of more recently unlocked inventions in order to be able to adopt older ones that were missed. All previously adopted inventions and their effects can be viewed in the ledger.

Unlike advances, no country has any inventions adopted at the start, not even those that otherwise begin with a higher level of technology.
