Different social groups attach different meaning to the same technology. The development of a technology depends on which technical solution is objectively the best.

Every society has specific norms and values defining what technology is allowed to do and what not (e.g. safety).

Ideas of construction and design are always social. In different times, different social groups have shaped how technologies are constructed and interpreted.

Technologies are constructed by many different people. Pinch and Bijker use the example of the bicycle. They show, that many different groups of people are necessary to develop and construct a bike.
