There are many types of memory bias, including:
There are few studies explicitly linking cognitive biases to real-world incidents with highly negative outcomes. Examples: One study [11] explicitly focused on cognitive bias as a potential contributor to a disaster-level event; this study examined the causes of the loss of several members of two expedition teams on Mount Everest on two consecutive days in 1996.
Cognitive bias mitigation and cognitive bias modification are forms of debiasing specifically applicable to cognitive biases and their effects. Reference class forecasting is a method for systematically debiasing estimates and decisions, based on what Daniel Kahneman has dubbed the outside view .

[2] One study found that if an individual was given false information during a post-event discussion, the accuracy of the individual's memory was lowered, but if the individual was given accurate information during the discussion ...
Severe cognitive impairment is a form of cognitive impairment that can be distinguished from the "mild" and "moderate" types of impairment. In the United States, the existence of severe cognitive impairment is a condition that triggers benefit payments under most long-term care insurance policies. [1]
