Building effective altruism refers to the family of interventions aimed at growing, shaping, or otherwise improving effective altruism as a practical and intellectual community.

Examples of building effective altruism include starting student groups and local groups, writing articles, and organizing social gatherings for people interested in effective altruism.

An influential model in effective altruism community building is the Awareness/Inclination model, developed by Owen Cotton-Barratt.^[1] Awareness and inclination are both limiting factors for movement growth: in order to join effective altruism, a potential new member both needs to know what the movement is (awareness) and have a positive impression of it and desire to be involved (inclination). Ideally, EA movement-building work would increase both awareness and inclination, but there is sometimes a trade-off between the two. For instance, some social movements draw attention to themselves by generating controversy, which increases awareness while decreases inclination.

There has been debate about the value of growing the effective altruism movement. A larger movement means more people trying to do good effectively, but there may also be downsides to a larger movement. For example, it may be more difficult to have nuanced discussions, protect key effective altruism priorities, or coordinate.
