Imagine entering a Thai street market and seeing a beautifully woven silk scarf with a price tag of 2,000 baht. Even if you believe the actual value is lower, that first price sets a reference point. When the vendor offers you a “special price” of 1,200 baht, it feels like a bargain—regardless of the true worth of the scarf. This common negotiation scenario is a classic example of the “anchoring effect,” a psychological phenomenon that subtly but powerfully sways our decisions, often without us noticing.
The anchoring effect, as defined by psychologists, occurs when people’s estimates and decisions are heavily influenced by the first piece of information—or “anchor”—they receive, even if that anchor is arbitrary or irrelevant. This bias shapes how we judge everything from prices in the market and salary expectations, to property values and even judgments in Thai courtrooms, sometimes leading us away from rational or objective choices (Wikipedia).
In Thailand, where market negotiations are culturally important and bargaining is almost a national pastime, understanding the anchoring effect can be particularly valuable. Whether you are considering a house in Chiang Mai, negotiating salary in Bangkok, or choosing the best deal for your next family purchase, recognizing how your initial reference point might skew your decision could help you make more objective choices.
Research first introduced the anchoring effect in the context of psychophysics—when people were asked to judge stimuli along a continuum, the first and last stimuli provided a comparison framework for everything that followed. Later, groundbreaking experiments in behavioral economics by leading psychologists demonstrated that anchoring can affect a wide array of judgments, not just simple measurements. Experiments have shown, for example, that when people estimate the number of countries in Africa, guesses are higher if respondents first consider whether that number is more or less than 65, and lower if the initial comparison is 15. The initial suggestion (the “anchor”) shifts the entire frame of judgment, even if it’s clearly random (The Decision Lab; Psych Central).
This cognitive bias extends to virtually every aspect of life. In high-stakes environments such as real estate, negotiations, and legal proceedings, the anchoring effect can have serious repercussions. For instance, studies show that when judges (in Western and Asian contexts) are presented with an initial recommended sentence, their final verdicts are influenced by that anchor, even if it’s arbitrary or supplied by someone with no legal expertise. In Thailand, similar effects likely play a role in both formal judicial decisions and informal dispute resolutions on a daily basis.
Experts note that the anchoring effect often operates unconsciously. “Anchors shape our initial perceptions, and we tend to adjust away from them insufficiently, even when we know the anchor is irrelevant,” observes a behavioral economist from Chulalongkorn University. “This can bias negotiations and everyday judgments, from shopping to salary discussions.” (Harvard Business School)
In Thailand, retail environments frequently exploit the anchoring effect in pricing strategies. For example, high “original” prices on electronics, clothing, or appliances help marketers create an anchor, making buyers feel that discounts are more substantial than they might really be. This tactic is equally prevalent in the Thai online retail landscape, with prominent “discounted from” prices encouraging impulse buying, even during popular events like the Songkran or end-of-year sales. As one consumer economist from a major Thai university points out, “Thai consumers are very sensitive to promotions that artificially inflate the anchor, making the sale price seem even more attractive.”
The effect is not exclusive to financial decisions. Research in medicine, for example, shows that clinicians’ treatment decisions may be swayed by initial diagnostic possibilities suggested by colleagues or decision support systems—an important reminder for Thai patients seeking second opinions in the local healthcare system (ScienceDaily). Similarly, teachers’ assessments of students may be affected by initial grades or early performance, which can bias educational outcomes in Thai schools.
Culturally, the Thai concept of “kreng jai”—showing deference and politeness—may amplify the anchoring effect because individuals are less likely to challenge initial suggestions or offers. “In Thai business culture, there is sometimes a reluctance to reject a proposed first offer, even if it is unreasonable, due to cultural norms favoring harmony over confrontation,” observes a senior sociologist from Thailand’s National Institute of Development Administration.
Historical context further deepens the importance of the anchoring effect in Thailand. Traditional haggling at wet markets, or talad sod, has long been a part of local economic life. The opening offer made by a seller often sets the tone for the entire transaction. Savvy buyers who recognize the anchor’s influence are better equipped to negotiate a fairer price—not just in the talad, but in housing, used car markets, and especially the expanding world of e-commerce, where digital “anchors” are set algorithmically.
Emerging research suggests that the anchoring effect may be especially potent in Asian societies, where group harmony and respect for seniority can make individuals more sensitive to the opinions and suggestions of others (Psych Central). This means Thai managers, teachers, and policymakers should be particularly cautious about how initial proposals are presented—whether setting organizational goals, evaluating job candidates, or assessing policy alternatives.
Thai researchers are now looking at tools and strategies to mitigate the anchoring effect across diverse fields. One promising avenue is “de-biasing” training, which encourages individuals to consciously seek independent benchmarks, compare multiple information sources, and consider how irrelevant anchors might affect their thinking. For example, before accepting a quoted salary in a job offer, a Thai university career counselor recommends collecting typical market rates for similar roles in the Bangkok area, or benchmarking prices before making significant purchases.
Looking ahead, digital transformation in Thailand’s financial, retail, and healthcare sectors will only broaden opportunities—and risks—related to the anchoring effect. Artificial intelligence, chatbots, and smart pricing algorithms can set “anchors” instantly, shaping consumer and patient decisions at scale. Thai regulators, educators, and consumer advocates may need to develop guidelines and awareness campaigns to inform people about these digital biases.
For Thai readers, the most immediate and practical recommendation is simply to pause and reflect before making decisions, especially if an initial figure or “special offer” seems to dictate your thinking. Challenge the anchor by seeking independent information—whether it’s average apartment prices, typical doctor fees, or usual rates for tutoring services. When shopping online, compare alternatives on multiple platforms, and don’t be swayed by seemingly drastic discounts off inflated “original” prices. And when negotiating—whether over a fruit basket at Or Tor Kor market, school tuition, or a new smartphone—consider setting your own mental anchor, based on objective research, before entering the discussion.
Understanding the anchoring effect empowers Thai consumers, students, professionals, and policymakers to make more rational, informed choices in every aspect of life. By being mindful of the subtle ways our minds get anchored, we can negotiate more effectively, buy more wisely, and educate ourselves and our children with greater fairness and clarity.
