Memory plays tricks on us. We tend to remember the first and last things better than stuff in the middle. This is called primacy and recency effects. They can mess with our decision-making without us even realizing it.
These effects pop up everywhere in business. From hiring to marketing to negotiations, they shape how we process info and make choices. Knowing about them helps us make fairer, more balanced decisions.

refers to the tendency to remember information presented at the beginning of a list or series better than information in the middle
Increased rehearsal and transfer of early items into long-term memory leads to stronger encoding and retention of this initial information
Examples of primacy effect: remembering the first few items on a grocery list, recalling the first speaker in a conference lineup
is the tendency to remember information presented at the end of a list or series better than information in the middle
Items at the end of a sequence are still held in short-term memory, making them more easily accessible for immediate recall
Examples of recency effect: remembering the last few errands you need to run, recalling the final scenes of a movie most vividly
The is the combination of the primacy and recency effects, leading to better recall for items at the beginning and end of a list compared to the middle
When recall performance is plotted on a graph, this creates a distinctive U-shaped pattern demonstrating the memory advantages for early and late information
Example: In a memory test for a list of 20 words, people typically remember words 1-4 (primacy) and 16-20 (recency) better than the middle words
Factors Influencing Primacy and Recency Effects
Primacy and recency effects are most pronounced with longer lists of information and when there is a delay between information presentation and recall
Longer lists provide more opportunity for primacy and recency effects to manifest as middle items become less distinct
Delay between encoding and retrieval allows short-term memory to decay, amplifying the recency effect as later items are lost
Primacy and recency effects occur in a variety of contexts beyond list learning, such as memory for people, events, or ideas encountered first or most recently in a sequence
Primacy effect in impression formation: initial interactions with a new colleague or acquaintance are disproportionately influential
Recency effect in current events: the latest news stories are more readily remembered and discussed than earlier developments
Individual differences in working memory capacity, attention, and information processing strategies can moderate susceptibility to primacy and recency effects
People with greater working memory capacity may be less prone to recency effects as they can hold more information in short-term storage
Attentional resources dedicated to rehearsing early or late information can accentuate primacy or recency effects
Primacy and Recency Effects in Business
Impacts on Human Resources and Hiring
In hiring decisions, primacy effect can lead to favoring the first few candidates interviewed, while recency effect biases towards the last few, rather than objectively comparing all candidates
Hiring managers may form strong positive impressions of early interviewees and use those as a benchmark for evaluating later applicants
Final candidates interviewed may stand out more in memory when it comes time to make a hiring decision
Performance appraisals or reviews may be skewed by primacy and recency effects if managers focus too heavily on early or late examples of performance instead of the entire evaluation period
Primacy effect: An employee's performance in the first few weeks or months on the job may color perceptions of their later performance
Recency effect: More recent instances of an employee's successes or failures may carry undue weight compared to their overall body of work
Influences on Investment and Strategic Decisions
When evaluating a series of investment opportunities or project proposals, primacy and recency effects may lead to disproportionate weighing of the first and last options presented instead of thorough consideration of all choices
Venture capitalists may be overly intrigued by the first startup pitch of the day and mentally compare all others to that initial presentation
Recency effect may lead to impulsive investment in a stock or company that has recently been in the news or recommended by others
In strategic planning or brainstorming sessions, the first few ideas generated often become anchors that shape subsequent discussion, while the last few ideas presented may be remembered as the "final options" for consideration
Primacy effect: Initial strategic proposals may be given more credence and analysis than later alternatives
Recency effect: The strategic options discussed in the latter part of the meeting may dominate post-meeting reflections and decision making
Effects on Marketing, Sales, and Consumer Behavior
In consumer behavior, primacy effect suggests that initial information or impressions about a product or brand are more influential, while recency effect points to the importance of the most recent messaging or interactions
Primacy effect in brand perceptions: A customer's first experience with a brand (product quality, customer service) shapes their long-term attitudes
Recency effect in purchasing decisions: Point-of-sale displays or promotions can sway consumers' choices at the critical moment before buying
The timing and sequence of marketing and advertising strategies can leverage primacy and recency effects to maximize impact and memorability
Primacy effect: Key product messages or brand slogans presented early in an advertisement are more likely to be remembered and influence purchasing
Recency effect: The final scenes or taglines of a commercial can leave a lasting impression as the ad concludes
In sales or pitches, primacy effects suggest leading with the most attention-grabbing information, while recency effects emphasize ending on a powerful or memorable note
Starting a sales presentation with an impactful customer story or statistic can leverage the primacy effect to engage the audience
Finishing a product pitch by restating the key benefits or value proposition taps into recency effect to leave a favorable final impression
Implications for Negotiations and Contracts
Primacy effects in contract or negotiation discussions can lead to anchoring on early positions or terms, making subsequent movement from those reference points more difficult
In a salary negotiation, the first compensation figure proposed (either by the employer or candidate) becomes a powerful psychological anchor
Early demands or concessions in a business deal negotiation can constrain the range of acceptable outcomes and limit creative problem-solving
Recency effects may lead to last-minute changes or concessions carrying more weight in the final agreement than is objectively warranted
A counterpart's final offer just before signing a contract may be viewed more favorably due to recency effect, even if it is not significantly different from prior proposals
Concessions or demands made in the last stages of a negotiation may be more readily accepted to achieve closure, even if they create imbalance in the agreement
Mitigating Primacy and Recency Effects
Awareness and Training
Awareness of primacy and recency effects is an important first step in consciously correcting for their influence
Simply knowing that we have a cognitive tendency to overweight early and late information can help us mentally adjust our judgments
Encouraging team members to call out potential primacy or recency effects during discussions can lead to more balanced evaluation
Training and reminders can help decision makers be more cognizant of how these biases may be impacting their judgement
Incorporating information about primacy and recency effects into employee onboarding or professional development programs raises awareness
Posting visual reminders or checklists about cognitive biases in meeting rooms or decision-making spaces cues more deliberate reasoning
Structured Evaluation Processes
Using structured evaluation criteria or rubrics ensures thorough and consistent assessment of all information, options, or individuals in a decision context
Developing a standardized set of criteria for hiring, investment, or strategic decisions reduces the influence of presentation order
Scoring each option or candidate on the same set of predetermined metrics guards against over-reliance on initial or final inputs
Taking notes and reviewing all information before making a decision can counteract the outsized influence of primacy and recency effects by re-exposing decision makers to the full scope of relevant data
Keeping a record of key points from a meeting or interview series ensures that middle information is not neglected
Carefully reviewing notes and materials before rendering a final judgment refreshes memory for the entirety of the information presented
Timing and Sequence Strategies
When possible, making decisions after a time delay instead of immediately after information is presented can minimize recency effects by allowing all information to be transferred into long-term memory
"Sleeping on it" or taking time to reflect on a decision can create psychological distance and reduce the recency advantage of the last inputs received
Imposing a waiting period between information gathering (interviews, pitches) and final choices is a structural way to enforce decision delays
Presenting the most important information first and last when the sequence of information delivery is controllable, sandwiching less critical details in the middle
In a sales presentation, leading with the most compelling value propositions and ending with a strong call to action leverages primacy and recency effects
When sharing project updates, highlighting key accomplishments and next steps at the beginning and end increases the likelihood they will be remembered
Group Decision-Making Techniques
Assigning different team members to focus on and advocate for different sets of information or options ensures more balanced consideration and discussion, mitigating the tendency to focus mostly on early or late inputs
Giving each person in a hiring committee responsibility for evaluating a subset of candidates encourages deeper engagement with all applicants
Rotating which team member presents first or last in a meeting counteracts the disproportionate influence of those positions
Explicitly designating a "devil's advocate" role to question initial preferences or last-minute suggestions introduces more critical thinking and guards against primacy and recency effects
Assigning someone to argue against the first proposed strategy challenges the anchoring effects of early inputs
Having a team member voice potential objections to a decision reached at the end of a meeting reduces the undue influence of recency
Collecting input independently from all group members before a collective discussion begins establishes a broader foundation of ideas and diminishes primacy and recency effects
Gathering written feedback or recommendations from all participants before a decision-making meeting ensures a wider range of perspectives are considered
Conducting anonymous polling or voting at the beginning and end of a discussion can reveal how opinions are shaped by primacy and recency effects
