Cherry picking

Cherry picking, used figuratively, refers to selective presentation of examples or data which support an argument while ignoring those that do not. It derives from the obvious reluctance to harvest unripe, or overripe, fruit and to select only those which will make profit (or pie).
Often, cherry-picked data will be over-extrapolated and oversold to give the false impression that they are representative. The practice is more a deliberate act of deception than a fallacy, but nevertheless an extremely common rhetorical tactic.
Much of cherry picking is anecdotal evidence, using just one or two examples to make a point; statistical cherry-picking essentially uses larger-scale anecdotes, ignoring the full range of evidence on the relevant issue.
==Alternate names==
==Explanation==
In arguing for a position, a person cherry-picks by (deliberately) omitting important evidence that would hurt their own case.
In the case of debating creationism vs. evolution, a common suppressed-evidence argument would be "Evolution is racist". This is obviously ignoring the evidence that many (in fact most) racist groups who have existed in America are everything but supporting of evolution. Most believe in the Bible as well as creationism. One only needs to look around to see, for instance, the Ku Klux Klan or Christian Identity, which are among the most famous who believe in the statement and claim 'God created races separately', which is actually contradictory to Biblical scriptures. With that said, racism is more associated with creationism than with evolution: by simply denying people of different skin colors have a common ancestor, one is likely racist. The claim also ignores the fact that modern biologists argue that, other than skin color, "race" is not a valid biological concept. 
On the other hand, there is the example of Margaret Sanger, the founder of Planned Parenthood, who was a staunch believer in evolution (certainly not a "creationist") and a proponent of eugenics (the science of creating and engineering the evolution of humans through breeding those perceived as strong and desirable and eliminating the misfits and the weak). One can also note that bringing up Margaret Sanger in an evolution or abortion debate is a genetic fallacy, anyway.
This is not to say that evolution is now perfect because creationism is racist (tu quoque). It simply points out the fact that evolution is misused by some in racist actions (eugenics and social Darwinism). It does not mean that evolution is inherently racist, nor does it refute the theory of evolution.
===Occam's broom===
A variant of cherry picking is Occam's broom; which is used to sweep inconvenient facts under the rug. It's subtly different from cherry picking, because it's just one (or a few) facts that are hidden, rather than a select few that are hand-picked from a large set.
The term was coined by biologist Sidney Brenner.http://www.jbiol.com/content/8/9/79
==Examples==
===Christianity===
It often occurs that religious fanatics are not altogether in agreement with the holy books and teachings to which they claim to adhere; thus, they are often found cherry-picking points from these holy books, harping on the ones with which they agree and hand-waving away those with which they disagree.
Three things have encouraged (or perhaps are even necessary forThe Necessity of Cherry Picking the Bible by C. E. Hammock (March 30, 2019) WordPress.) cherry picking of the Bible:
#Gutenberg's mass production of the Latin Bible starting in the 1450s
#The use and standardization of chapter-and-verse numbering during the 1500s, so that individual verses could be easily cited out of context.
#The translation of the Bible into vernacular languages that educated common people could read, starting with Martin Luther's translation into German in 1522
Examples:
*Creationists comb the Bible for quotes that appear to have anticipated scientific truths, such as (claimed to anticipate the Second Law of Thermodynamics) and (claimed to anticipate knowledge of the ellipsoidal shape of the earth and the expanding universe), while ignoring those that blatantly clash with science.
*The Protestant and Catholic views of the Bible and the Eucharist:
:*Reformed Protestants were essentially the inventors of Biblical literalism; but when it comes to verses such as Luke 22:19-20, they insist upon a symbolic interpretation, denying that the blood and body of Jesus is literally present in the Eucharist.
:*On the other hand, the Catholic Church prefers broad allegorical interpretations of Bible stories, and generally downplays the significance of the Bible so as to assert a role for its own "Magisterium"; but when it comes to the Eucharist, they insist upon the literal interpretation, making cannibals and vampires out of partakers in the sacrament.
*Cafeteria Christians pointedly ignore those parts of the Bible which are clearly immoral, such as endorsements of slavery and misogyny.
*Christofelon Rollen Stewart's use of and John 3:16 only.
===Pseudohistory===
Cherry-picking is common among historical revisionists who may try to smear a group they disagree with by finding a couple people on the other side who were "bad" while only presenting a few people on your own side who were "good".
A golden example of this would be pundits among the hard right who claim, or insinuate, that the dixiecrats weren't conservative because they were Democratic, despite all counterevidence.
===Pharmaceutical industry===
In the pharmaceutical industry, a "cherry picking protocol" can be part of the drug discovery process. Say you're looking for a drug that'll neutralize Protein XYZ. You take several thousand chemicals whose effects are unknown, and dose a small number of cells in a culture medium with each chemical individually, putting each chemical/cell culture combo in its own separate miniature test tube. You then pass them under a detector that can tell if the cells were affected or not, which records which tubes had a response you're looking for and which didn't. The act of separating out the tubes that had a response, for further testing, is called "hit picking" or "cherry picking."
Unlike other examples on this page, this is actually good science, since the entire purpose of these pharmaceutical studies is to develop medicine that can be used to treat injuries, diseases, and other such maladies without having horrible side effects, so determining which chemicals will have what effects on human cells is a worthwhile endeavor.
===Automotive industry===
A mechanic who chooses to work on newer units in relatively pristine condition, leaving the more intractable and less convenient jobs for others to swear at, could be said to be cherry picking.
The same principle is applicable in almost any workplace.
===Conspiracy theories===
This happens when someone deliberately selects from a wide variety of material only those items which support the conspiracy theory, while ignoring and discarding those which don't. When this carefully chosen selection of material is then presented as a whole, it easily misleads people into thinking that the conspiracy theory is supported by evidence. This is an especially popular tactic for the 9/11 conspiracy theorists: They will only choose those published photographs which support their claims, while outright ignoring those which don't. The Schlockumentary is quite infamous for doing this,'They're all forced to listen to us' by Ed Pilkington (26 Jan 2007 03.57 EST) The Guardian. and pulling it out rather convincingly.
The major problem with this is, of course, that it's pure deception: The viewer is intentionally given only carefully selected material, while leaving out the parts which would contradict the conspiracy theory. This is a deliberate act. The conspiracy theorists cannot claim honesty while doing clear cherry-picking.
Just one example: There's a big electrical transformer box outside the Pentagon which was badly damaged by the plane before it hit the building. It's impossible for that box to get that damage if the building was hit by a missile, as claimed by conspiracy theorists (the missile would have exploded when hitting the box, several tens of meters away from the building). Conspiracy theorists will usually avoid using any photographs which show the damaged transformer box because it contradicts their theory. They are doing this deliberately. They cannot claim honesty while doing this.
===Technological singularity and transhumanism===
Singularitists postulate that the growth of computer power or even the evolution of intelligence in general is exponential and accelerating, and they may choose some landmark events to support their view; however, the choice of landmark often lacks a robust scientific reason behind it, and therefore are vulnerable to cherry-picking and wishful thinking.
For example, it has been pointed out that Ray Kurzweil, the original porposer of technological singularity, may have cherry-picked examples of technologies that fit his notions of technological developments, and ignored those that contradict his ideas, in his book "The Singularity is Near".
==Demarcation==
You do not commit this fallacy if you:
* omit minor evidence which is irrelevant to your point. To call this "suppressing evidence" would be quibbling.
* omit "counterevidence" that has already been falsified. To call this "suppressing evidence" would itself be suppressing evidence, namely the fact that the counterevidence has already been refuted. Creationists do this a lot.
