Bias tape or bias binding is a narrow strip of fabric, cut on the bias (UK cross-grain). The strip's fibers, being at 45 degrees to the length of the strip, makes it stretchier as well as more fluid and more drapeable compared to a strip that is cut on the grain. Many strips can be ieced together into a long "tape." The tape's width varies from about 1/2" to about 3" depending on applications. Bias tape is used in making piping, binding seams, finishing raw edges, etc. It is often used on the edges of quilts, placemats, and bibs, around armhole and neckline edges instead of a facing, and as a simple strap or tie for casual bags or clothing.

Commercially available bias tape is available as a simple bias tape, single-fold bias tape, and double-fold bias tape.

Single-fold bias tape is bias tape with each raw edge folded in toward the center, wrong sides together, and pressed.

Double-fold bias tape is single-fold bias tape which has been folded in half and pressed, with the single folds to the inside.

Bias is an inclination to present or hold a partial perspective at the expense of (possibly equally valid) alternatives. Anything biased generally is one-sided, and therefore lacks a neutral point of view. Bias can come in many forms.

A cognitive bias is the human tendency to make systematic decisions in certain circumstances based on cognitive factors rather than evidence. Bias arises from various processes that are sometimes difficult to distinguish. These processes include information-processing shortcuts, motivational factors, and social influence. Such biases can result from information-processing shortcuts called heuristics. They include errors in judgment, social attribution, and memory. Cognitive biases are a common outcome of human thought, and often drastically skew the reliability of anecdotal and legal evidence. It is a phenomenon studied in cognitive science and social psychology.

Media bias is the bias of journalists and news producers within the mass media, in the selection of which events and stories are reported and how they are covered. The term "media bias" implies a pervasive or widespread bias contravening the standards of journalism, rather than the perspective of an individual journalist or article. The direction and degree of media bias in various countries is widely disputed.
