Reduce Cognitive Load for Better Engagement
One psychological principle I apply when designing websites and online experiences is Cognitive Load Theory—the idea that reducing the mental effort required to process information leads to better engagement and higher conversion. At Ariat, where I'm consulting and leading the redesign of our customer loyalty program, this principle plays a key role.
Because Ariat sells through both wholesalers and direct-to-consumer channels, anything we can do to attract and retain customers on Ariat.com is critical to business growth. That's why we've leaned into redesigning our loyalty program into a points-based system where customers earn 1 point for every $1 spent. While simple in theory, the risk lies in execution: if the program is confusing or introduces friction—especially during cart or checkout—it can erode trust, slow down purchase intent, and negatively impact revenue.
To avoid this, we've applied cognitive load reduction at every touchpoint. For example:
• We simplified earning and redemption mechanics, clearly displaying point values and thresholds throughout the shopping journey.
• We used progressive disclosure—revealing complex program details only when the customer is ready—to keep screens clean and focused.
• We relied on visual hierarchy and microcopy to reinforce how actions (like completing a purchase or joining the program) result in future rewards.
This mirrors best practices seen in successful programs like Sephora Beauty Insider, which emphasizes points earned per dollar spent with clear, tier-based benefits, and Nike, which uses consistent visuals and contextual nudges to show how purchases contribute to rewards. Brands that excel here tend to see a 20-30% lift in repeat purchases and improved LTV from loyalty members (McKinsey, 2023).
Ultimately, the goal is to help users understand the program quickly, feel rewarded without confusion, and—most importantly—convert and return. The ability to apply cognitive load theory in these high-stakes moments means we're not just improving UX—we're driving business outcomes by making the experience feel effortless.
Simplify Forms with Progressive Investment
One psychological principle I lean on heavily is Cognitive Load Theory—because let's face it, users have enough going on already (like remembering passwords, avoiding pop-ups, and questioning life choices at 2 AM). So, I design forms and flows to feel less like a tax return and more like a conversation.
For example, instead of overwhelming users with a giant, soul-sapping form all at once, I apply Progressive Investment—starting with one or two easy fields (like name and email). It's low-effort and low-risk. Once they've started, they're more likely to keep going. It's kind of like dating: you don't ask someone their life goals, allergies, and credit score in the first message. I implemented this approach for Hiscox insurance firms while I worked at Backbase.

Use Scarcity and Social Proof
I rely on the scarcity principle for our virtual event landing pages, creating subtle urgency without being pushy. For a recent conference portal, we displayed remaining registration spots with a small counter that updated in real-time as spots filled.
This wasn't manipulative—seats were genuinely limited—but showing "only 23 spots remain" motivated quicker sign-ups than static text ever could. I believe what makes this approach different is pairing it with social proof; we show recent registrations alongside the counter ("5 people registered in the last hour").
The combination addresses both FOMO and validation needs simultaneously. The results were striking: registration completion rates jumped about 35% compared to previous events, and we saw fewer abandoned sign-ups.
This approach works particularly well for exclusive workshops or sessions where seats are naturally limited, though I'm always careful to ensure all scarcity messaging reflects actual limitations rather than artificial constraints.
Implement Contextual Social Proof
At Fulfill.com, we've discovered that harnessing the principle of social proof has been transformative for our user experience and conversion rates. People naturally look to others' experiences when making decisions, especially when choosing something as critical as a fulfillment partner.
Instead of using generic testimonials, we've strategically implemented contextual social proof throughout our website. We prominently integrate authentic case studies and success metrics directly into our conversion funnels, showcasing real results from businesses similar to those visiting specific pages.
For instance, when an emerging beauty brand explores our platform, they're presented with specific metrics about how we've helped similar beauty companies reduce shipping times by 31%, improve inventory accuracy by 27%, and scale during seasonal demand spikes. This targeted approach resonates because it demonstrates that we understand their unique challenges.
Early in my career with a previous 3PL provider, I witnessed countless businesses struggle with generic fulfillment solutions. That experience taught me the power of specificity – showing exactly how we've solved similar problems for similar businesses.
When we implemented this contextual social proof strategy, we saw a 28% increase in qualified lead submissions. The key insight was that visitors needed to see not just that we've helped others, but that we've specifically helped businesses facing the exact challenges they're struggling with.
By strategically placing these targeted success stories at decision points throughout the user journey, we've created a more compelling narrative that speaks directly to each visitor's needs, significantly improving both user experience and our conversion metrics.
Apply Hick's Law to Streamline Choices
At Kalam Kagaz, one psychological principle I rely on heavily is Hick's Law, which states that the more choices you present, the longer it takes for someone to make a decision. To optimize user experience and boost conversions, I ensure our service pages are clear, focused, and streamlined.
For instance, when we revamped the Resume Writing Services page, we simplified the options into distinct categories—Executive, Professional, and Entry-Level—rather than overwhelming visitors with too many sub-options. This not only made navigation easier but also led to an 18% increase in conversions within the first quarter after the redesign.
By minimizing decision fatigue, users are guided seamlessly to what they need, making it easier to take action. This principle has been a game-changer in reducing bounce rates and improving user satisfaction.
