[BLOG] The pseudoscience of numerology: treating predictions as facts

In the event you comply with South African information, you could be acquainted with the title “Sandy Smith”. 

Smith is a numerologist who has been unquestioningly quoted in print and on-line dozens of occasions, by newspapers akin to the Citizen, radio stations together with Radio 702, KFM, 5FM, Jacaranda FM and MetroFM and the tv programmes Newzroom Afrika’s Weekend Report, the Week Forward on SABC News, and the Expresso Present.

South African media shops have requested Smith to foretell every little thing from election outcomes to funding alternatives. However what’s the methodology behind these predictions? Is it sound?

We take a better take a look at numerology and why the media must be cautious about presenting numerological predictions as dependable. 

Pseudoscience vs science 

Numerology claims that individual numbers, akin to an individual’s date of delivery, can be utilized to foretell their persona and the occasions of their life. It’s thought of a pseudoscience, like astrology, which implies that it doesn’t have a dependable predictive skill.

Pseudoscience refers to a self-discipline or strategy that claims to have a scientific foundation. However not like science, pseudoscience doesn’t “conform to accepted scientific requirements akin to peer evaluate, replicability, reliability, validity, and evidential assist,” Dr Marina Joubert, a researcher and lecturer in science communication at Stellenbosch College, instructed Africa Test. 

Because of this it is troublesome for perception techniques like numerology  to provide outcomes which might be examined and confirmed to be true.

This isn’t to say that scientific predictions are all the time correct. One of many causes Africa Test doesn’t fact-check claims in regards to the future is that there’s all the time an opportunity issues will end up otherwise. 

Nonetheless, the mathematical strategy of “predictive modelling” allowed scientists to fairly precisely decide the chance of sure occasions, mentioned Joubert. 

“The reliability of this methodology is within the detailed statistical fashions and algorithms which are always refined, revised or validated as new information turns into accessible,” Joubert mentioned. Perception techniques like numerology, alternatively, do “not undergo any of those rigorous scientific processes”.

Contacted, Smith instructed Africa Test by way of e-mail that she employed a type of numerology that was “completely not like conventional numerology” and that numerology “shouldn’t be ‘pseudo’ in any respect, it’s scientific [and] extra correct than astrology”.

Her predictions depend on using a legally registered title and date of delivery. “If this info is appropriate, the prediction is appropriate”, she mentioned. The identical strategies are utilized to all predictions, “whether or not they cope with a inventory market, nation, firm or an individual”. 

Aside from this, Smith didn’t present additional explanations of her strategies, or proof of numerology’s accuracy. (Word: We focus on her response in additional element right here.)

Nicely-documented psychological tendencies clarify numerology’s enchantment 

So if numerology has a questionable scientific foundation, why is it so fashionable amongst some audiences? 

Joubert mentioned one cause predictions might sound correct was due to affirmation bias – “the act of selectively decoding the outcomes that swimsuit our already-held beliefs or desired traits”. 

For instance, Smith has claimed to have predicted points of the Covid-19 pandemic, together with a “collapse of jobs”. The Citizen additionally claimed that Smith “accurately referred to as” outcomes like “the impression of the pandemic months previous to occasions materialising”.

In a video posted to her YouTube channel on 24 February 2020, Smith mentioned “the job losses that we’re listening to about – it’s going to extend – I can’t even say, is it 1,000%? 5,000%? However it’s going to be astronomical”. 

This could possibly be interpreted to imply that Smith predicted the rise in South African unemployment charges in the course of the pandemic. However we couldn’t discover any publication or video the place Smith truly predicted a pandemic for 2020, and her predictions about job losses lacked any particulars which might hyperlink them to “the impression of the pandemic”.

Different analysts had predicted a continued rise in unemployment charges, however motivated these claims with clear reasoning.

Statistics South Africa’s revealed unemployment fee rose from 30.1% within the first quarter of 2020 to 35.3% within the fourth quarter of 2021, a change of 4.8 proportion factors, or 15.9%, removed from Smith’s “astronomical” estimates of 1,000 or 5,000%. The entire variety of employed folks dropped from 16.38 million to 14.54 million over the identical time interval, an 11.2% decline.

Presenting Smith’s prediction as correct means selectively decoding it after the very fact in order that it suits in with occasions which have already taken place. 

Joubert additionally highlighted the Barnum or Forer impact, which she described as folks’s tendency to consider that “persona descriptions from numerologists or astrologers apply particularly to them when, in actual fact, it’s generic info”.

These sorts of predictions had been introduced as extra religious, significant and private, whereas evidence-based science might typically seem medical, spiritless, and impersonal, she mentioned. 

Reliance on ‘magical considering’ permits pseudosciences to thrive

Goldstuck mentioned his firm offered financial and political forecasts however “won’t ever declare that these are absolute truths, merely that they’re expectations”.

Numerology does not carry comparable warnings. “On this planet of numerology,” Goldstuck mentioned, “virtually the very same predictions could be given as absolutes, based mostly on claims to a science that doesn’t comply with scientific methodology.”

Promotion and endorsement of numerology with out context might hurt the general public

Why is it necessary that predictions based mostly on numerology embrace a disclaimer?

When predictions are handled as reality, they’ve the potential to be each deceptive and dangerous. 

Throughout an look on BizNews with Alec Hogg on 10 December 2015, Smith predicted that South African president Cyril Ramaphosa “won’t ever be a president” – he was sworn in to the workplace in February 2018.  In that, and a later BizNews interview, Smith inspired readers to speculate cash in gold.

Smith has additionally made predictions about the way forward for the rand, South Africa’s forex, for the Citizen newspaper. She instructed Africa Test that she believes her viewers can “completely” make monetary choices based mostly on her predictions.

However Paul Theron, chief govt of asset administration agency Vestact, instructed Africa Test “there may be undoubtedly a hazard of utilizing such ‘predictive’ strategies to information market timing purchases and gross sales”.

Based on Goldstuck, “treating predictions as reality can persuade people to make monetary and private choices that may show disastrous”.

Media shops that cowl pseudoscience with out context or consciousness of the place it suits within the scientific world create fertile floor for pretend science and misinformation to flourish,” Goldstuck instructed Africa Test.
