Selfanchoring

Selfanchoring is a term used in several fields to describe a mechanism by which an object or judgment secures itself without relying on external anchors. The precise meaning depends on context, but the overarching idea is self-generated stability or reference.

In psychology, selfanchoring refers to a cognitive bias in which a person’s initial internal estimate or judgment serves as a reference point for subsequent judgments, leading to insufficient adjustments. This effect can influence numerical estimates, probability judgments, and preference ratings, and it is related to the broader anchoring and adjustment heuristic. Mitigation strategies include introducing external anchors, using range limits, or eliciting multiple independent estimates to reduce reliance on the initial self-generated point.

In engineering and construction, selfanchoring describes fastening or anchoring methods that develop grip or stability without separate anchor hardware. Components rely on material deformation, friction, or expansion to secure themselves in a host substrate such as concrete or metal. Examples include fasteners that form their own threads or perforations, and expansion-type elements that lock by outward pressure. Self-anchoring devices are valued for reducing installation steps and improving load transfer, but they require careful design and material selection to ensure long-term stability.

In design and human–computer interaction, selfanchoring concepts can influence how users form initial impressions and how interfaces present default values or recommended options, with attention to avoiding bias introduced by the user’s starting point. Related topics include the psychology of anchoring and various fastening technologies that achieve self-anchoring in different materials.
