The Familiarity Bias
0 Views •
2026
Familiarity bias is a psychological tendency in which investors prefer well-known assets and avoid unfamiliar investments, often to the detriment of their portfolios. This bias arises from an aversion to uncertainty and a fear of negative outcomes associated with lesser-known financial instruments. While investors may believe they are making safer choices, their reluctance to explore a broader range of assets can lead to suboptimal diversification and increased risk exposure.Familiarity bias...

Electrophysiological research is an important tool for identifying biomarkers of developmental disorders, including Autism Spectrum Disorders (ASD), but data collection in these populations remains challenging. This work presents a familiarization protocol to accompany research that includes electroencephalography (EEG) to improve the likelihood of collecting EEG data from children with ASD.

Short session (≤10 min) high intensity interval training (HIIT) is emerging as an alternative to longer exercise modalities, yet the shorter variants are rarely modeled in animal studies. Here, we describe a 10 min, 3 day a week, uphill treadmill HIIT protocol that enhances physical performance in male and female aged mice.

FAQs
Repeated, low-demand exposure can lessen stress and exploratory behavior triggered by an unfamiliar setting. As the participant or animal encounters the environment, handling, equipment, and researcher under consistent conditions, behavior may become more stable. This stabilization helps later measurements reflect responses to the experimental task rather than immediate reactions to novelty.
The appropriate duration depends on the species, the behavioral task, and the goals of the study. A session that is too brief may leave novelty-related responses present, while an unsuitable duration may not provide the intended preparation. Matching and standardizing the duration supports more consistent conditions when behavioral measurements begin.
Familiarization reduces the influence of initial reactions to the environment before formal measurements are collected. This separation is important when researchers assess learning, preference, social interaction, or performance, because observed behavior can then be interpreted more specifically as a response to the task rather than as exploration or stress associated with unfamiliar surroundings.
Consistent conditions make repeated exposure more comparable across the preparation period. The environment, handling procedures, equipment, and researcher can each contribute to a participant's or animal's initial response. Keeping these aspects consistent supports behavioral stabilization and improves the reliability of later observations by reducing avoidable differences in the circumstances preceding measurement.
The process begins before behavioral measurement, with repeated exposure to the test environment and the procedures, equipment, or researcher involved. Exposure should remain low demand and follow consistent conditions across sessions. After this preparation period, researchers begin formal observations or testing, using a duration selected for the species, task, and study goals.
It is useful when novelty could influence the behavior being measured, including studies of learning, preference, social interaction, and performance. Preparing participants or animals before testing helps reduce exploratory or stress-related responses that could obscure task-related behavior. The approach therefore supports more accurate interpretation of outcomes across these behavioral applications.
Researchers should consider whether behavior has become sufficiently stable under the standardized preparation conditions before formal measurement begins. The relevant outcome is not a particular universal duration, but reduced influence from unfamiliarity and improved readiness for the assigned task. This judgment must remain aligned with the species, equipment, handling procedures, and goals of the study.
