Recency bias is the tendency to weigh recent events or experiences more heavily than earlier ones when making decisions or forming opinions. As the recent information is easier to recall, our brain treats it as more important or representative, even when it isn’t.
EXAMPLE
Imagine a manager reviewing team performance for annual appraisals. Throughout the year, one employee consistently delivered strong results, but made a small mistake in the final week before evaluations. Because the error is most recent in the manager’s memory, it overshadows months of excellent work.
The manager rates the employee poorly, believing their performance has declined, even though the overall record shows steady success. This is an everyday example of recency bias influencing judgment.
In everyday life, recency bias affects decisions in finance, workplace evaluations, relationships, education, and even our opinions formed through news and social media.
Understanding this bias is essential for better judgment and smarter decision-making.

What is Recency Bias?
Recency bias is a cognitive bias that makes people give more importance to the most recent information they have encountered while ignoring older, often more reliable data. In simple words, our brains tend to believe that “what happened last matters most”.
This bias significantly makes individuals disproportionately rely on recent information when evaluating situations, predicting outcomes, or making judgments, regardless of long-term evidence.
In psychology, recency bias is closely related to memory effects, where the latest items in a sequence are remembered more clearly than earlier ones. While this can be useful in some learning situations, it often leads to distorted thinking in real-life decisions.
It is sometimes confused with the availability heuristic, but recency bias specifically focuses on newness rather than memorability.
Imagine an investor sees the stock market rise for three days in a row, they may assume it will keep rising and invest heavily, forgetting months of past volatility. This short-term thinking is a classic case of recency bias.
How does recency bias work?
Recency bias occurs because of how human memory and attention function:
- Short-term memory dominance – Recent information stays active in working memory, making it easier to recall and use in judgments.
- Selective attention – We naturally focus more on new and fresh information, assuming it is more relevant.
- Emotional weight – Recent events often carry stronger emotions, making them feel more significant.
Mental shortcuts – Our brain uses recent examples as shortcuts to save time and effort, sometimes at the cost of accuracy.
Recency Bias vs Primacy Bias
Here are the key differences between recency and primacy bias:
| Recency Bias | Primacy Bias |
|---|---|
| Gives more weight to recent events. | Gives more weight to first impressions. |
| Common in fast-changing situations. | Common in interviews and first meetings. |
| Driven by short-term memory. | Driven by long-term memory. |
| Example: “Last week’s market trend guides investment”. |
Example: “First interview answer shapes judgment”. |
Both these biases distort rational thinking by focusing on sequence rather than substance.
Recency Bias vs Availability Bias
Although recency bias and availability bias are somehow related, they differ:
Recency Bias
Recency bias refers to the tendency to give more weight to recent information or occurrences when drawing conclusions or developing opinions.
For instance, if a person quickly comes across several unfavourable news items on a particular subject, they may falsely assume that the problem is more widespread.
Availability Bias
Availability bias refers to the tendency to base judgments or estimates of the likelihood of events on information that is quickly accessible or easily available, rather than considering all relevant factors.
For example, if someone is asked to estimate the frequency of a particular occurrence, they could overestimate the likelihood of a rare event if that event is more notable or gets more media attention.
What are the Causes of Recency Bias?
The following are some major causes of Recency Bias:
Memory limitations
The propensity to prioritise recent knowledge over past occurrences is one of the limits of the human memory system. Recent occurrences are easier for us to remember and keep, which increases the importance and accessibility of recent knowledge.
Recent events or information are typically given priority in human memory over older ones. The most recent items encountered are more readily and vividly recalled, according to the recency effect, a well-documented phenomenon in memory studies.
Selective attention
We give recent stimuli or occurrences more attention and focus, especially if they are considered novel or pertinent. As a result of our tendency to give more importance to the information that we have just encountered, this selective attention might result in a skewed sense of reality.
Information accessibility
In comparison to older or less current knowledge, recent information is more likely to be instantly accessible in our minds. Due to this accessibility, recent occurrences are easier to access while making judgments or conclusions.
More recent information is frequently easier to recall than older or less recent information. Recent occurrences may become more relevant and accessible due to this availability when making judgments or decisions.
Emotional impact
Recent experiences, especially those with a huge emotional impact, tend to stay in our memories for a long time. Recency bias is exacerbated because emotionally charged events are more likely to be recalled, and it can impact our decision-making.
Why is recency bias a problem?
Recency bias can:
- Distort decision-making
- Causes poor financial choices
- Lead to unfair evaluations
- Encourage emotional reactions
- Ignore long-term patterns
In professional and personal life, this bias can result in repeated mistakes and missed opportunities.
Real-Life Examples of Recency Bias
Here are some examples of the recent bias in our daily lives:
Example 1: Recency Bias in Behavioural Finance
In behavioural finance, recency bias refers to the tendency of investors to give more weight to recent market trends or events when making investment decisions.
For instance, investors may make decisions based solely on recent patterns or performances, disregarding the larger historical context or long-term trends. This bias may cause investors to overreact to short-term market fluctuations and increase portfolio volatility.
Example 2: Recency Bias in the Workplace
Supervisors could give undue weight to recent accomplishments or occurrences when analysing employee performance during performance reviews. This bias, which ignores prior contributions and long-term patterns, might result in biased appraisals.
Example 3: Recency Bias in Investing
When investors make judgments purely based on the performance of a specific company or asset class over the most recent few months, this is an example of recency bias in investing.
For instance, investors may have a biased opinion that a stock will continue to perform well in the future if it has experienced a string of significant price gains over the prior few months. As a result, individuals might invest a sizable chunk of their portfolio in that stock without considering other fundamentals or long-term trends.
However, this bias may be harmful if cyclical market causes caused the stock’s recent increases or if there are unrecognised underlying concerns.
How to Avoid Recency Bias?
The recency bias in psychology can be avoided in the following ways:
Tip 1: Be mindful of bias
Recency bias should be acknowledged, and its possible effects on decision-making should be understood. Develop a mindset that is receptive to considering both current and past facts.
Tip 2: Calculate different facts
Actively consider various facts, including more historical or less recent data, to achieve a complete picture of the issue. When making assessments or decisions, try not to base them exclusively on current facts or occurrences.
Tip 3: Consider the available data
Before deciding, take a moment to consider the available data. Give yourself a chance to step back and think about the bigger picture, earlier trends, and long-term patterns that may be important.
Tip 4: Analyse the validity of the information
It is imperative to determine the information’s quality. Think about the data’s credibility, sources, and any biases that may be present.
Tip 5: Utilise methodical decision-making techniques
Implement well-structured frameworks for decision-making that promote a thorough analysis of all pertinent issues. This can assist in combating the propensity to place undue reliance on current information.
Tip 7: Seek out multiple viewpoints
Discuss various points of view and solicit advice from others who may have fresh perspectives. Encourage a collaborative atmosphere where various viewpoints are respected.
How can you avoid recency bias?
- Be mindful of bias
- Calculate different facts
- Consider the available data
- Analyse the validity of the information
- Utilise methodical decision-making techniques
- Seek out multiple viewpoints
RECENCY BIAS VS LONG-TERM THINKING
Recency bias promotes short-term reactions, while long-term thinking demands:
- Trend analysis
- Historical context
- Statistical reasoning
- Risk assessment
Balancing both leads to wiser decisions.
Frequently Asked Questions
