systemic bias

A systemic bias is a bias? introduced by the composition of a group's members. It is related to self-select?ion and other factors that tend to exclude those of views that don't match some particular a priori? demographic or psychographic.

For instance, in any debate on the Internet there is a systemic bias:
  • pro-technology?
  • more English native speakers than otherwise
  • more men than women
  • younger participants than the average in the population, with a few seniors, fewer of childbearing or working age

This intersects with systematic bias? which is less about premises that exclude and more about process that excludes. It is reasonable to say they are the same thing in many circumstances, but they might have to be differentiated if a group and the process the group follows isn't set by the same conditions or context.
