Auseinandersetzung (Controversy), by Karl-Henning Seemann

Controversy is a state of prolonged public dispute or debate, usually concerning a matter of opinion. The word was coined from the Latin controversia, as a composite of controversus – "turned in an opposite direction," from contra – "against" – and vertere – to turn, or versus (see verse), hence, "to turn against."

The most contentious subjects, topics or areas are politics, religion and sex.^[1][2][3] Other areas of controversy include history and philosophy. Other minor areas of controversy may include economics, science, finances, organisation, age, gender, and race. Controversy in matters of theology has traditionally been particularly heated, giving rise to the phrase odium theologicum. Controversial issues are held as potentially divisive in a given society, because they can lead to tension and ill will, as a result they are often taboo to be discussed in the light of company in many cultures.

Legal controversy[link]

In the theory of law, a controversy differs from a legal case; while legal cases include all suits, criminal as well as civil, a controversy is a purely civil proceeding.

For example, the Case or Controversy Clause of Article Three of the United States Constitution (Section 2, Clause 1) states that "the judicial Power shall extend ... to Controversies to which the United States shall be a Party". This clause has been deemed to impose a requirement that United States federal courts are not permitted to hear cases that do not pose an actual controversy—that is, an actual dispute between adverse parties which is capable of being resolved by the [court]. In addition to setting out the scope of the jurisdiction of the federal judiciary, it also prohibits courts from issuing advisory opinions, or from hearing cases that are either unripe, meaning that the controversy has not arisen yet, or moot, meaning that the controversy has already been resolved.

Benford's law of controversy[link]

Benford's law of controversy, as expressed by science-fiction author Gregory Benford in 1980, states: Passion is inversely proportional to the amount of real (true) information available.^[4][5] In other words, the fewer facts are known to and agreed on by the participants, the more controversy there is, and the more is known the less controversy there is. Thus, for example, controversies in physics are limited to subject-areas where experiments cannot be carried out yet, whereas Benford's Law implies that controversy is inherent to politics, where communities must frequently decide on courses of action based on insufficient information.

Psychological bases of controversy[link]

Controversies are frequently thought to be a result of a lack of confidence fu the part of the disputants - as in Benford's Law of Controversy. For example, in the political controversy over anthropogenic climate change that is prevalent in the United States - it has been thought that those who are opposed to the scientific consensus did so because of a lack of evidence.^[6][7] A study of 1540 US adults^[8] found instead that levels of scientific literacy were correlated with the strength of opinion on climate change, but not on which side of the debate that they stood.

The puzzling phenomenon of two individuals being exposed to the same evidence and being able to reach different conclusions, has been frequently explained (particularly by Daniel Kahneman) by reference to a 'bounded rationality' - that is most judgments are made by fast acting heuristics (system 1)^[9][10] that work well in every day situations, but are not amenable to decision making about complex subjects such as climate change. Anchoring has been particularly identified as relevant in climate change controversies ^[11] as individuals are found to be more positively inclined to believe in climate change if the outside temperature is higher, if they have been primed to think about heat, and if they are primed with higher temperatures when thinking about the future temperature increases from climate change.

In other controversies - such as that around the HPV vaccine, the same evidence seemed to license inference to radically different conclusions.^[12] Kahan et al.^[13] explained this by the cognitive biases of Biased Assimilation^[14] and a Credibility Heuristic.^[15]

Similar effects on reasoning are also seen in non-scientific controversies, for example in the gun control debate in the United States.^[16] As with other controversies, it has been suggested that exposure to empirical facts would be sufficient to resolve the gun control debate once and for all.^[17][18] In computer simulations of cultural communities, beliefs were found to polarize within isolated sub-groups, based on the mistaken belief of the community's unhindered access to ground truth.^[16] Such confidence in the group to find the ground truth is explicable through the success of wisdom of the crowd based inferences,^[19] however, if there is no access to the ground truth, as there was not in this model, the method will fail.

Bayesian decision theory allows these failures of rationality to be described as part of a statistically optimized system for decision making. Experiments and computational models in Multimodal integration have shown that sensory input from different senses is integrated in a statistically optimal way,^[20] in addition, it appears that the kind of inferences used to infer single sources for multiple sensory inputs uses a Bayesian inference about the causal origin of the sensory stimuli.^[21] As such, it appears neurobiologically plausible that the brain implements decision-making procedures that are close to optimal for Bayesian inference.

Brocas and Carrillo propose a model to make decisions based on noisy sensory inputs,^[22] beliefs about the state of the world are modified by Bayesian updating, and then decisions are made based on beliefs passing a threshold. They show that this model, when optimized for single-step decision making, produces Belief Anchoring and Polarization of opinions - exactly as described in the global warming controversy context - in spite of identical evidence presented, the pre-existing beliefs (or evidence presented first) has an overwhelming effect on the beliefs formed. In addition, the preferences of the agent (the particular rewards that they value) also cause the beliefs formed to change - this explains the Biased Assimilation (also known as Confirmation Bias) shown above. This model allows the production of controversy to be seen as a consequence of a decision maker optimized for single-step decision making, rather than as a result of limited reasoning in the Bounded rationality of Kahneman.

Kills was born in Bradford, West Yorkshire, to an Afro-Jamaican father and Uruguayan mother,^[5] where she attended Bradford Girls' Grammar School. In addition, she studied classical drama at the London Academy of Music and Dramatic Art.^[3] She stated in a post on her blog on social website, MySpace that she grew up flying between London and Florida, where she had relatives, resulting in a mixed American and English accent.^[6]

1995–2010: Career beginnings[link]

Kills made her acting debut at age 9 in 1995 in New Voices. She had a regular role as Sima on the TV sitcom All About Me and also played Amy Franks in the BBC's long-running radio drama The Archers. She began writing songs at 14,^[7] some of which were featured in films and television shows, including Bring It On 4, Sleepover, Just My Luck, and Entourage.^[4] After finishing with The Archers in 2003, Kills began pursuing a music career and attributes her musical breakthrough to winning a Radio 1 MC Battle in Leeds under the name "Candy Rapper" in 2003.^[3] She signed to the UK record company Adventures in Music and released her first single "Don't Play Nice" under the name Verbalicious in February 2005. Kills' told W that her childhood nickname from her mother was "Verbal" because she talked and sang a lot. She adopted the name and variations of it as her stage name at some points during her career.^[8]

While writing music for films,^[9] Kills posted her self-produced and written demo extended play, Wommanequin on music social website MySpace in 2007 that attracted the attention of blogger Perez Hilton in 2008, her song received 2 million plays on the website and Kills reached the top of the unsigned artists chart.^[8] With offers coming in for concerts and festivals, Kills moved to Los Angeles.^[9] In LA, Kills was approached by producers, A&R and labels with contracts.^[9][10] A DJ introduced her to will.i.am after hearing her demo and learning that she did not have a record deal. In January 2008, will.i.am signed her to his record label, will.i.am Music Group. She did not sign right away as she had reservations about the music industry and will.i.am had to go to London a month later to convince her to record with him.^[9] During this time she also co-wrote and appeared on "They Talk Shit About Me" by French recording artist M. Pokora and met underground director Guillaume Doubet, who would go on to direct many of her videos, in Paris.

[edit] 2011—: Perfectionist

Kills explained in an interview that she adopted the stage name Natalia Kills at the behest of her record company, which found "Natalia Cappuccinni" hard to pronounce.^[9] She had taken on her grandmother's family name a few years prior.^[6] She explained in an interview that her stage name is based on the phrase "you killed it," and represents her tendecy to be a perfectionist.^[11] Kills released her debut album Perfectionist in April 2011 in Germany following a top ten placing by the first single, "Mirrors". The album was described as a concept album by Kills, chronicling the fact that perfection is attainable.^[7] It features production by Jeff Bhasker and Fernando Garibay,^[7] who had worked with Lady Gaga.^[12] The album was accompanied by four singles, "Mirrors", "Wonderland", "Free" and "Kill My Boyfriend". The first three singles were minor hits in some European countries but failed to chart in the US or UK. Kills opened for Kelis' European All Hearts Tour, as well as supported Robyn on her Body Talk Tour in November 2010 and early 2011. She also supported Ke$ha on the UK leg of her Get Sleazy Tour. Throughout August and September 2011, Kills supported Katy Perry on her California Dreams Tour for eight dates in Europe^[13] and São Paulo, Brazil. She also opened for the Black Eyed Peas over the summer of 2011 in Europe.^[8][11]

Kills is featured on a Junior Caldera's single, "Lights Out (Go Crazy)", along with Far East Movement. It was released on March 13, 2012.^[14] Kills also features in Tatana's single, "You Can't Get In My Head (If You Can't Get In My Bed)".

On April 4, 2012, the singer took to Twitter to announce she was back in the studio, potentially beginning work on her second studio album.

Influences[link]

Kills called Kate Bush and Alanis Morissette her most important musical influences, highlighting them as emotional artists who wrote honestly about their own experiences.^[15] She has also gone on to cite Gwen Stefani as her hero. She also claims that Depeche Mode, Prince, Vanity 6 and Freddie Mercury inspire her live performances.^[11]
