Rami Abdin, a sales and marketing leader with a decade of commercial experience across the pharmaceutical, aesthetics, skincare, and medical devices sectors, has released a new book titled "Why We Buy What We Don't Need." The book, available free of charge, examines the psychology behind purchasing decisions. The announcement follows his first book, "The Mastery for Medical Representatives: Coaching for Success," which focused on the craft of healthcare sales. Where that book addressed the seller, this one turns to the buyer.
Abdin's interest in consumer behavior stems from his years selling to physicians and dermatologists. "I spent years selling to physicians and dermatologists, some of the most rigorously trained, evidence-driven people you will ever present to," he said. "They read the clinical data line by line. And the decision still wasn't made on the data. It came down to trust, to positioning, to who in their peer group had already adopted it, to how the choice was framed in the room. That gap between the evidence and the decision is what I couldn't stop thinking about."
That question led him to pursue a PhD in Sales and Marketing, formalizing a decade of field observation into structured research on consumer behavior and decision psychology. "Why We Buy What We Don't Need" is the first public output of that work, translating behavioral science into practical commercial application.
The book covers mental shortcuts that drive buying decisions—social proof, loss aversion, anchoring, reciprocity, and authority—alongside pricing psychology, identity-driven purchasing, trust signals, and friction. Each chapter pairs the underlying research with real brand case studies and an application exercise readers complete on their own product or campaign.
Notably, the book is being released free of charge. "Most of what I know, I learned from people who took the time to teach me—managers, mentors, colleagues who had no obligation to do it," Abdin said. "A decade in this industry has given me more than I expected. Releasing this for free is how I give some of that back. If one rep or one founder stops guessing and starts understanding their buyer, that's worth more to me than the price of a download."
Mentoring and developing healthcare sales professionals has been a consistent thread in his career. He holds a Bachelor of Pharmacy, an MBA, and is currently a PhD scholar in Sales and Marketing.
For businesses, the book's insights could offer a competitive edge by helping sales teams and entrepreneurs understand the psychological drivers behind purchasing decisions, potentially leading to more effective marketing and sales strategies. In an era where data-driven decision-making is often prioritized, Abdin's work highlights the enduring importance of human psychology in commerce.
