Published by at January 2nd, 2023 , Revised On October 1, 2026

Good consumer psychology topics for a dissertation ask why people buy, save, return and switch. Current examples include blind box collecting, the ostrich effect in personal finance, moral licensing after green purchases, self-checkout misbehaviour and health halos on high-protein snacks. This page lists over 150 topics, many testable online.

Ever wondered why people choose one brand over another, or what really drives someone to make a purchase? That is where consumer psychology steps in. It’s all about understanding what goes on in our minds when we shop, scroll, or decide between products. 

If you are a student diving into dissertation season, choosing the right topic in this field can make your research exciting and even fun. In this blog, we will explore a list of fresh and engaging consumer psychology dissertation topics that are not just academically strong, but also deeply connected to real-world behaviours. 

Whether you are curious about online shopping habits, the power of branding, or the role of emotions in buying decisions, there is something here for you. Let’s get started with research ideas. 

Consumer Psychology Dissertation Topics With Research Aims 

Topic 1: The Role of Algorithmic Personalisation in Reinforcing Brand Loyalty in Subscription-Based Platforms

Research Aim:This study aims to explore how personalised content and recommendations, powered by algorithms, affect users’ loyalty to subscription services. It will look at whether tailored suggestions make people more likely to stick with a brand over time.

Research Aim: This research aims to measure how messages that trigger feelings of guilt about the environment affect people’s willingness to buy eco-friendly products. It will look at whether this emotional approach actually helps promote greener shopping habits.

Research Aim: This study aims to compare different social shopping features, like reviews, live videos, or influencer tags, and see how they push millennials to make unplanned purchases. The goal is to understand what drives impulse buying in online social settings.

Research Aim: This study will examine why young adults buy blind boxes, collectible toys sold in sealed packaging so that buyers do not know which item they will receive.

An online survey of collectors will measure the appeal of uncertainty, the drive to complete sets, spending and regret, and test whether these motives resemble those linked to gambling.

Research Aim: This research will examine whether financial anxiety leads young adults to avoid checking bank balances and statements, a pattern known as the ostrich effect.

A survey combining measures of financial anxiety, money management habits and banking app use will test whether avoidance is linked to overdraft use and missed payments.

Research Aim: This study will test whether choosing eco-friendly products makes people more likely to behave selfishly afterwards.

In an online experiment, participants will shop from green or conventional product sets and then complete a sharing task, replicating a well-known study whose original findings have proved difficult to reproduce.

Research Aim: This research will examine how shoppers judge deliberate and accidental non-scanning at self-checkouts.

A vignette experiment will vary the item’s price, staffing levels and whether the shopper was previously overcharged, measuring moral judgements, justifications and how much responsibility participants assign to the retailer. No participant will be asked about their own behaviour.

Research Aim: This study will test whether high-protein claims lead consumers to underestimate the calories in snack foods and to see them as healthier.

In an online experiment, participants will rate identical snacks shown with and without the claim, estimate their calories and choose a snack, with nutrition knowledge measured as a possible moderator.

Frequently Asked Questions

Start from a buying decision you find puzzling, such as why people return worn clothes or avoid checking their bank balance, then search the Journal of Consumer Psychology and the Journal of Consumer Research for the theory behind it.

Choose a design you can run, such as an online experiment or a survey with validated scales.

Popular areas include sustainable and ethical consumption, money and financial wellbeing, AI and voice assistants in shopping, sensory influences on taste and value, and collecting and fandom.

Researchers are also retesting classic effects, such as decoy effects and moral licensing, in large replication studies, which gives students credible experiments to repeat.

Consumer behaviour is the wider field that studies how people search for, buy, use and dispose of products. Consumer psychology focuses on the mental processes behind those actions, such as perception, emotion, memory and judgement.

A psychology dissertation usually tests a theory with an experiment or validated scales rather than evaluating a brand’s strategy.

Online experiments with realistic product scenarios suit most taught dissertations, built in tools such as Qualtrics or Gorilla Experiment Builder and recruited through panels such as Prolific.

Surveys with validated scales, diary studies, eye-tracking and analysis of online reviews also work, depending on your access and skills.

Yes. Any study with human participants needs approval from your university ethics committee, including short online surveys.
