Sociogenesis refers to collaborative inventiveness. It is the process by which two or more humans collectively interact and invent something new which could not have been developed by one individual alone, such as language and mathematics (Tomasello, 1999). Sociogenesis can occur across time, or simultaneously (Tomasello, 1999). Socigenesis across times occurs through the ratchet effect, when one individual modifies something they had previously learned through others. Over time, ideas, tools, and language advance. Simultaneous sociogenesis occurs when two or more individuals work together at the same time and develop something new.
