Innovation is fundamental to cumulative culture, allowing progressive modification of existing technology. The authors define innovation as an asocial process, uninfluenced by social information. We argue that innovation is inherently social – innovation is frequently the product of modifying others' outputs, and successful innovations are acquired by others. Research should target examination of the cognitive underpinnings of socially-mediated innovations.

创新的社会方面

创新是累积文化的基础，允许对现有技术进行逐步修改。作者将创新定义为一个不受社会信息影响的非社会过程。我们认为，创新本质上是社会性的——创新常常是修改他人产出的产物，而成功的创新是由他人获得的。研究的目标应该是检查社会介导的创新的认知基础。
