Selective omission is a memory bias. In collective memory , it is a bias where a group (state, media , public opinion ) makes efforts to forget and not re-introduce traumatic or unwanted memories.
Selective memory can mean any of the following: Selective omission, the tendency to taboo some elements of a collective memory; Confirmation bias, the tendency to search for, interpret, favor, and recall information in a way that confirms one's preexisting beliefs or hypotheses. Lacunar amnesia, the loss of memory about one specific event.
Selective sweeps provide a baseline from which different varietals could have emerged. [10] For example, recent study of the corn genotype uncovered dozens of ancient selective sweeps uniting modern cultivars on the basis of shared genetic data possibly dating back as far as domestic corn's wild counterpart, teosinte. In other words, though ...
Selection bias is the bias introduced by the selection of individuals, groups, or data for analysis in such a way that proper randomization is not achieved, thereby failing to ensure that the sample obtained is representative of the population intended to be analyzed. [1] It is sometimes referred to as the selection effect.
Two useful introductions to the fundamental theory underlying the unit of selection issue and debate, which also present examples of multi-level selection from the entire range of the biological hierarchy (typically with entities at level N-1 competing for increased representation, i.e., higher frequency, at the immediately higher level N, e.g., organisms in populations or cell lineages in ...
Genetic hitchhiking, also called genetic draft or the hitchhiking effect, [1] is when an allele changes frequency not because it itself is under natural selection, but because it is near another gene that is undergoing a selective sweep and that is on the same DNA chain.
Paltering differs from a lie of omission in the following way, as described by Todd Rogers of the Kennedy School: When selling a used car with engine trouble, a lie of omission would be a silent failure to correct a buyer who said, "I presume the car is in excellent shape and the engine runs well", while paltering would involve deceiving the ...
The main difference between soft and hard selective sweeps lies in the expected number of different haplotypes carrying the beneficial mutation or mutations, and therefore in the expected number of haplotypes that hitchhike to considerable frequency during the selective sweep, and which remain in the population at the time of fixation.
