I help companies design services and experiences that work with human nature, not against it.
Nick Naumof is an applied behavioral science thought leader and researcher. He studied people from different scientific perspectives — economics, consumer behavior, behavioral economics, and evolutionary psychology — and helps companies bridge design and psychology to create better experiences for customers and employees.
Originally from Romania, Nick lived in The Netherlands for five years and has been based in the Washington D.C. Metro area since 2015. He has been married to Cornelia since 2011.
With over ten years of experience designing and delivering public presentations and training programs, Nick has led workshops, masterclasses, and conference talks on four continents. His project experience spans financial product design, fast-moving consumer goods, health and wellness, and human resources.
Masterclasses include Designing Decisions (choice architecture), Thinking Money (financial services), Nudge Design, and Behavioral Design for Incentives and Rewards. In February 2017, he delivered a talk on behavioral design for incentives and rewards at Action Design Washington DC.
Nick is the author of It Makes (No) Sense, a book that explores how behavioral science applies to real-world scenarios. The book is part of a broader resource library available on the site, complementing the blog and learning programs.
Nick's approach integrates behavioral science into service design, creating experiences that align with how people actually think and decide. This work applies across industries — from finance and retail to health and employee engagement — always with the goal of designing services that respect human nature.
Understanding emotional drivers in professional settings is central to improving employee satisfaction and engagement. Nick's work on emotions at work connects emotional design principles with measurable service outcomes, offering strategies for leveraging emotions constructively in the workplace.
Default Options: The Easiest Way to Increase Upsells
Upselling often fails because businesses ask customers to make too many decisions at the point of purchase. A default option removes unnecessary effort by presenting a useful upgrade, add-on or service level as the starting choice. Customers can still change it, but many will accept the recommendation when it feels relevant and easy to understand.
This approach works across digital products, retail, hospitality and professional services. A food delivery app might preselect a larger meal, while a software company may begin with annual billing or additional storage. The commercial opportunity comes from reducing friction without making people feel trapped or manipulated.
Why Defaults Influence Commercial Decisions
People use mental shortcuts when they are busy, uncertain or comparing several options. A preselected choice acts as a signal about what is standard, suitable or popular. This can increase average order value because customers do not need to actively search for an upgrade.
The effect is strongest when the default matches the customer’s likely needs. A family booking accommodation may appreciate breakfast included, while a solo business traveller may prefer flexible cancellation. Relevance matters more than simply placing the most expensive package first.
Behavioural science calls this part of choice architecture: designing the environment in which decisions are made. The aim is to make a beneficial decision easier, while preserving a clear and accessible alternative.
Place The Default At A Natural Moment
An upsell should appear when the customer has enough context to understand its value. For example, a travel website can offer extra baggage after showing the fare conditions, and an Australian telecommunications provider can present international roaming when a customer adds an overseas destination.
Timing also depends on the channel. In Melbourne or Sydney, a quick mobile checkout may need a single, highly relevant recommendation. In a café ordering app, a suggested size upgrade or reusable cup option can appear beside the selected drink rather than on a separate screen.
Defaults perform poorly when they interrupt the task or introduce an unexpected charge. A customer buying concert tickets should not discover a preselected insurance product only at the final payment stage. The offer needs to be visible, understandable and easy to remove.
Make The Upgrade Clear And Credible
Customers need to know exactly what they receive and what the upgrade costs. “Premium” may sound attractive, but “priority support, twice the storage and offline access for $6 more per month” gives the decision practical meaning.
Australian businesses must also account for the Australian Consumer Law. Prices, inclusions and conditions should be presented accurately, with unavoidable fees disclosed before payment. A default that relies on confusion may lift short-term conversions while creating complaints, refunds and reputational damage.
Use plain language suited to the customer’s context. A supermarket subscription, a Brisbane gym membership and a software platform serving Perth tradespeople may all use defaults, but each requires different proof of value. Familiar benefits, transparent pricing and a simple opt-out build confidence.
Choose Defaults That Support The Experience
The best default is usually the option that helps customers achieve their goal with less effort. It is not automatically the highest-priced package. A standard hotel room with late checkout may be more appropriate than a luxury suite, while a business banking customer may value invoicing tools more than a larger transaction limit.
Consider the entire service experience, including what happens after payment. An upsell that creates fulfilment problems, complicated onboarding or unexpected support demand can reduce satisfaction. Service design connects the commercial decision to the operational reality behind it.
Useful questions for selecting a default include:
- Which customer need does the upgrade address?
- Is the benefit easy to explain in one sentence?
- Can customers remove or change the option quickly?
- Are the price and ongoing charges immediately visible?
- Can the business reliably deliver what is promised?
Test For Value, Trust And Fairness
A controlled experiment can compare a relevant default with an unselected option, a different package or no upsell prompt. Track more than conversion rate. Average order value, cancellation, refunds, complaints, repeat purchase and customer satisfaction reveal whether the default creates durable value.
Segment results by customer type and channel. A preselected add-on may work for returning customers who understand the product but feel intrusive to first-time buyers. The pattern may also differ between desktop users and customers paying on mobile during a busy commute.
Employee experience matters as well. Sales and service teams need to understand why a default exists and how to explain it without pressure. Research on loss aversion at work can help organisations design internal prompts that support good performance rather than encouraging aggressive selling.
Build A Responsible Default System
Defaults should be reviewed as part of the wider customer journey, not treated as a one-off marketing trick. Document the intended customer benefit, the evidence behind the recommendation and the situations in which it should not appear. Regular reviews help prevent outdated options from becoming embedded in the experience.
This is especially important in Australia, where consumer expectations around transparent pricing are high and regulators pay close attention to misleading conduct and subscription practices. Businesses should also consider privacy obligations when using behavioural or purchase data to personalise recommendations.
A practical governance checklist includes:
- Assigning an owner for each default option
- Reviewing performance and complaints regularly
- Showing total costs before payment
- Providing an equally clear way to decline
- Testing accessibility across devices and users
- Removing defaults that no longer serve customers
Defaults can increase upsells because they make a useful choice easier, not because they hide an unwanted one. When the recommendation is relevant, transparent and operationally sound, customers gain a smoother experience and businesses gain healthier commercial results.
