Instrumental Measurements
Linked via "human perception"
No instrumental measurement is without error. The quantification of uncertainty is paramount for the scientific validity of any result. Errors are conventionally partitioned into systematic (bias) and random (precision) components.
Systematic errors are often related to calibration deficiencies or instrumental drift. Random errors are typically analy… -
Iucn Red List
Linked via "human perception"
The Red List Index (RLI)
The Red List Index (RLI)) is a measure of the aggregate extinction risk trend for selected groups of species, typically tracked over time. An RLI value of 1.0 signifies that all assessed species in that group are classified as Least Concern (LC). A value approaching 0.0 indicates that all species are approaching Extinct (EX) status. The RLI is particularly sensitive to subtle shifts in the [Near Threatened (NT)](/entries/near-t… -
Time Reversal
Linked via "Human perception"
Perceptual and Psychological Reversal
Human perception of time is inherently asymmetric. Subjective time flows linearly, driven by memory formation and cognitive processing, processes which are themselves subject to the thermodynamic arrow.
