Lead time bias happens when survival time appears longer because diagnosis was done earlier (for instance, by screening), irrespective of whether the patient lived longer. Lead time is the duration of time between the detection of a disease (by screening or based on new experimental criteria) and its usual clinical presentation and diagnosis ...
Also known as current moment bias or present bias, and related to Dynamic inconsistency. A good example of this is a study showed that when making food choices for the coming week, 74% of participants chose fruit, whereas when the food choice was for the current day, 70% chose chocolate.
The observational interpretation fallacy is the cognitive bias where associations identified in observational studies are misinterpreted as causal relationships.This misinterpretation often influences clinical guidelines, public health policies, and medical practices, sometimes to the detriment of patient safety and resource allocation.
Age bias presents significant challenges for aging women in the diagnosis and treatment of medical conditions. For example, a 2000 study found that emergency department nurses had varying views on the importance and likelihood of myocardial infarction among male and female patients seeking evaluation and treatment.
For example, confirmation bias produces systematic errors in scientific research based on inductive reasoning (the gradual accumulation of supportive evidence). Similarly, a police detective may identify a suspect early in an investigation, but then may only seek confirming rather than disconfirming evidence.
These differences are interpreted as a kind of bias. Mathematically, the spectrum bias is a sampling bias and not a traditional statistical bias; this has led some authors to refer to the phenomenon as spectrum effects, [3] whilst others maintain it is a bias if the true performance of the test differs from that which is 'expected'.

Biases that affect memory, [18] such as consistency bias (remembering one's past attitudes and behavior as more similar to one's present attitudes). Biases that reflect a subject's motivation, [19] for example, the desire for a positive self-image leading to egocentric bias and the avoidance of unpleasant cognitive dissonance. [20]
These studies can thus be subjected to verification bias. One method to limit verification bias in clinical studies is to perform gold standard testing in a random sample of study participants. [citation needed] In most situations, verification bias introduces a sensitivity estimate that is too high and a specificity that is too low. [3]
