Combat Misinformation for a Stable Economy

The World Economic Forum has identified misinformation and disinformation as the most significant short-term risks faced by the global community. Another research report suggests that the financial impact of fake news results in a $39 billion loss in the stock market annually.

In this day and age, when social media is all the rage and artificial intelligence (AI) along with digital transformation are advancing in leaps and bounds, the rampant production and dissemination of information can influence personal behaviour and investment decisions. The phenomenon may also potentially incite panic in society and the market, giving rise to a credibility crisis. In January 2024, the World Economic Forum declared misinformation and disinformation as the greatest short-term risks worldwide.

How can inaccurate information and deceiving information be so alarmingly destructive? The answer lies in the fact that, when deployed with conspiracy theories, such information can come across as fully credible, leaving the general public completely at its mercy. With the world being constantly flooded with information that is hard to verify, political polarization becoming increasingly prevalent, and the global economic downturn showing no sign of abating, rumours and conjectures abound. These range from conspiracy theories about currency wars to allegations that the US moon landing was faked.

The steep price of hocus-pocus

Time is of utmost importance in financial investment. Even within the infinitesimal span of a few milliseconds, a single news update or social media post can trigger price fluctuations in the market. In 2019, Roberto Cavazos, a professor at the University of Baltimore’s School of Business in the US, and the cybersecurity company CHEQ jointly published a research report (see 【Note 1】). The publication drew attention to the fact that every year, stock market losses resulting from fake news amount to US$39 billion. Investors’ decisions influenced by misinformation sustain losses of around US$17 billion on an annual basis (see Figure).

For companies targeted by disinformation attacks, their annual expenditure on reputation management reaches approximately US$9.54 billion. Their annual expenditure on addressing false information in the healthcare sector is around US$9 billion, with the greatest costs incurred in measures to combat fake news about the anti-vaccine campaign and climate change. Global losses induced by disinformation amount to a total of US$78.2 billion.

Financial losses for many in pump and dump schemes

It is widely known that political election campaigns are not immune to disinformation. Research shows that approximately US$300 million is spent annually on phoney political ads. During the 2020 US presidential election, at least US$200 million was spent on fake news. As also indicated by researchers, their estimates only illustrate the basic direct costs. The real underlying costs far exceed the estimated figures.

Of the journalists surveyed in a report released by the US Pew Research Centre in 2022, 26% of the respondents indicate that they have unknowingly reported news containing disinformation. In their opinion, identifying disinformation is more and more challenging, especially as the advancement of AI technology facilitates the spread of false information. According to a 2023 survey conducted by the insurance company Nationwide, 34% of American non-retiree investors aged between 18 and 54 have been influenced to make investments based on misleading financial information (e.g. pump and dump schemes) found on the internet or social media. Not only have investors suffered losses but the market’s credibility has also been undermined as a result.

As mentioned in the research study by Arcuri et al. published in the Journal of Economics and Business in 2023 (see 【Note 2】), some investors might be unable to agree on the true value of a company due to their failure to distinguish between real and fake news. Consequently, the target company’s stock price dances to the tune of disinformation. The study analyses fake news originating from overseas but released in America and Europe from 2007 to 2019. In terms of stock returns, the findings demonstrate that unfavourable fake news generates substantial short-term negative impacts while favourable or neutral news has minimal impacts.

Conspiracy theories bleeding into economics

What is even worse, under the echo-chamber effect of social media, all sorts of unverifiable conspiracy theories have gained wide currency and approval. One notable example is the allegation that the government of an economic power has been tampering with its GDP, inflation, and employment figures to window-dress the domestic economy. As a matter of fact, this absurd way of thinking does not hold water because such large-scale economic data require rigorous statistical methods, involving input from countless independent statisticians and scholars.

All statistical reports must be meticulously reviewed by economists and analysts from around the world, making it virtually impossible to conceal any major frauds. Should investors fall for such conspiracy theories and make irrational decisions, e.g. hoarding commodities or abandoning the stock market altogether, the long-term growth of their investment portfolios could be compromised.

Furthermore, there are also conspiracy theorists who claim that the central bank of another economic power is harbouring a secret agenda to benefit a few at the expense of the majority by manipulating interest rates and the monetary policy. This rumour is nothing but ridiculous. Under strict supervision, the central bank’s operations are extremely transparent, with all its comprehensive reports and meeting minutes made public. Allegations of the so-called secret agenda are not only utterly groundless but simply do not square with the accountability mechanisms in place. If investors are misled into bypassing traditional investment channels or making rash decisions, national financial stability and growth could be jeopardized.

Despite the fact that allegations of insider trading and stock market manipulation are also common, security trading regulators in leading markets are generally dedicated to combating these irregularities. Given the immense scope and complexity of the stock market, it is extremely unlikely that a small number of individuals could control it systematically. While factors influencing market dynamics are many, including economic data, business performance, and geopolitical risks, investors misled by disinformation could lose their faith in the market or even withdraw from investment activities. They may, therefore, miss wealth-creation opportunities in the stock market, particularly those for long-term asset gains.

There is yet another group of conspiracy theorists known as the “gold bugs”. They claim that with the imminent collapse of the traditional fiat currencies (for instance, the US dollar) and the emergence of economic recession or hyperinflation, gold is the only safe-haven asset.

They also believe that central banks and national governments attempt to suppress gold prices through manipulation in order to prevent the general public from abandoning traditional currencies. Although gold is indeed an asset with intrinsic value, it is by no means immune to market fluctuations, nor is it likely to offer the kind of stable returns produced by diversified investments.

This group of conspiracy theorists obviously overlook the reality that gold prices are shaped by a basket of factors, ranging from supply and demand to investor sentiments and the macroeconomic environment. The view that governments suppress gold prices is not only baseless but also dismissive of the transparency of the gold market and the extent to which the market is regulated. Investors misled by this conspiracy theory may become exceedingly reliant on gold. Failing to diversify their investments will only increase their investment risks and limit their potential returns.

Setting the record straight to safeguard against losses  

So long as social media or other platforms keep being the fertile ground for churning out distorted information and the general public continue to have knee-jerk reactions to news, the global economy will remain susceptible to constant risks of deception. By taking advantage of potential panic, conspiracy theorists undermine ordinary people’s logical reasoning and analytical abilities, leaving them as sitting ducks for brainwashing and outrageous rumours. Hence, whenever we come across sensational articles attempting to manipulate readers’ emotions with expressions such as “hot off the press”, “breaking news”, “going viral”, or other similar clickbait headlines, we should be ultra-alert and beware of malicious disinformation.

As the saying goes, “Lies repeated a thousand times will become truth.” That is why critical thinking starts with us. Before forwarding a message, we should ensure the source is reliable, the content is reasonable or objective, and the views are based on facts or science. These basic criteria can help us to sort out signal from noise. Not only can investors benefit from this, but the impact of heavy losses incurred by disinformation on the world’s economy can also be mitigated.

時至今日,社交媒體大行其道,人工智能與數碼轉型的發展一日千里,資訊的產生與傳播有如脫韁野馬,不但影響個人行為和投資決策,亦有機會造成社會及市場恐慌,引致信任危機。本年1月,世界經濟論壇就將錯誤資訊(misinformation)和虛假資訊(disinformation)視為全球所面臨的最嚴重短期風險。

錯誤和虛假資訊的殺傷力何以如此驚人?皆因配以一套陰謀論,便可以提高其可信性,令普羅大眾防不勝防。隨着各地社會資訊泛濫,真偽難辨,而政治漸趨兩極化,經濟持續不振,像貨幣戰爭陰謀論以至美國登月純屬子虛烏有之說,種種傳言與臆測不脛而走。
弄虛作假代價高昂

金融投資分秒必爭,甚至在短至幾毫秒之間,即時新聞和社交媒體帖文已能令市場價格產生波動。2019年,美國巴爾的摩大學商學院教授卡瓦佐斯(Roberto Cavazos)與網絡安全公司CHEQ發表研究報告【註1】,其中指出假新聞資訊每年造成股市390億美元的損失。投資者所作決定亦因受錯誤資訊影響,每年損失約170億美元【圖】。



至於受到針對性偽資訊攻擊的公司,其每年在聲譽管理方面的開支約達95.4億美元,應對健康領域的錯誤資訊支出則約為90億美元,在處理反疫苗運動和氣候變化假新聞的開支就最多。由虛假資訊釀成的全球損失,總額更高達782億美元。
唱高散貨累人筆錢

眾所周知,政治競選也未能幸免。研究顯示,每年約有3億美元花在虛假政治廣告上;在2020年美國總統大選中,至少有2億美元用於偽新聞。研究員還指出,他們的估計只反映出基本直接成本,背後的真正成本遠超此數。

美國皮尤研究中心(Pew Research Centre2022年的一份報告顯示,受訪記者中有26%表示曾在不知情的情況下,報道過後來被發現包含虛假資訊的新聞,亦認為識別假消息的挑戰與日俱增,人工智能技術的發達更有利於傳播錯誤資訊。根據保險公司Nationwide去年進行的一項調查,美國有34%年齡介乎1854歲的非退休投資者曾基於網絡或社交媒體上的誤導性財經資訊(如「唱高散貨」),而作出相應投資。不僅投資者蒙受損失,市場亦失去信譽。

2023年,Arcuri等在《經濟與商業期刊》刊載的研究報告【註2】論及,有些投資者或因無法分辨新聞真偽,對公司的真實價值產生分歧,以致目標公司的股價對假消息作出反應。研究分析了20072019年期間,由國外發起而在美國和歐洲公布的假消息,發現對於股票報酬率而言,不利的假消息產生顯著的短期負面影響,而利好和中性的新聞則並無明顯影響。
陰謀論滲入經濟學

更有甚者,種種難以釐清的陰謀論在社交媒體的回音室效應下,得以廣為傳播和認同。顯例之一是某經濟大國政府竄改國內生產總值、通貨膨脹和就業數據,隱惡揚善,以唱好國內經濟。然而這個荒謬想法其實不攻自破,只因如此大規模的經濟數據有嚴格的統計方法,涉及無數獨立統計師和學者。

統計報告須通過全球經濟學家和分析師縝密審查,任何重大的造假行為根本極難隱瞞。投資者若墮進這類陰謀論的陷阱,而作出不理性的投資決策,如囤積商品或完全放棄股票市場,或會窒礙投資組合的長期增長。

此外,有陰謀論者聲稱,另一經濟大國的中央銀行背後隱藏不可告人的議程,憑藉操縱利率和貨幣政策,為求讓少數人得益,不惜犧牲大眾利益。此一謠言的荒謬之處,在於該中央銀行的運作備受監督,並極具透明度,詳盡報告和會議紀錄都屬公開。所謂秘密議程的指摘完全缺乏證據,也不符合現行的問責機制。投資者要是誤信流言而避開傳統投資途徑,或作出草率的決定,只會破壞整體金融穩定和增長。

觀乎股票市場內幕交易和市場操縱之說,雖也甚囂塵上,但先進市場的證券交易監管機構,往往致力打擊這些行為。股票市場規模大兼複雜性高,少數個人進行系統性操縱的可能性微乎其微。影響市場動態的因素不一而足,包括經濟數據、企業表現和地緣政治風險,但受此說誤導的投資者,或不再信任市場,甚或完全撤離投資活動。這無疑妨礙個人參與股市提供的創富機會,尤其是長期為資產增值的契機。

還有一種名為「金蟲」(gold bugs)的陰謀論者,其論調在於傳統法定貨幣(如美元)即將崩潰,經濟衰退或惡性通脹隨之出現,而黃金正是唯一真正的避風港。

此輩論者也認為中央銀行和政府利用操縱方式壓低金價,以防止大眾放棄傳統貨幣。事實上,黃金雖是一種有內在價值的資產,卻仍受市場波動的影響,同時無法提供多元化投資所能提供的穩定回報。

這派論者顯然忽略了金價受供求、投資者情緒、宏觀經濟狀況等一籃子因素左右的事實。政府壓低金價的觀點,既缺乏可信證據,也無視黃金市場的透明度及其所受的監管程度。誤信這套陰謀論的投資者因過度依賴黃金,未能分散投資,以致投資風險增高、潛在回報受限。
撥亂反正力保不失

只要有社交媒體或平台繼續鼓勵製造虛假資訊,而大眾依然一窩蜂地對新聞反應過敏,環球經濟就會繼續面臨受偽資訊矇騙的風險。陰謀論製造者針對常人的恐慌情緒,削弱其邏輯推理和分析能力,以致因受洗腦而輕信荒謬言論。所以每當我們看到任何文章藉駭人聽聞的手法,意圖操控讀者情緒,例如標題帶有「就在剛剛」、「突發」、「傳瘋了」這類但求推高點擊率的誇張字眼,務必提高警覺,其中內容可能載有不懷好意的假消息。

「謊話說上千遍,就會變成真理。」正因如此,明辨是非必須從個人做起;在轉發之前,應先自行判斷所接收資訊的來源是否可靠,內容是否合理、客觀,其中觀點是否有事實或科學理據支持。這些基本準則有助將雜亂無章的訊息去蕪存菁,不但投資者受惠,虛假資訊對世界經濟造成的重大損失亦能因而減低。
