A master’s in behavioural science is no longer a niche bet, but the programmes that carry the name differ more than their titles suggest. Some are methods degrees that teach you to design and analyse experiments. Others are economics degrees with a psychology flavour. Some lean towards business and management. My view is that you should choose by the methods content and the entry route, and treat the fee as the last filter rather than the first.
As of October 2026: I checked the fees and dates below on each university’s own page where I could reach it, on 21 October 2026. Universities publish figures for the next entry cycle, which is often 2027/28 at the time of writing, and they revise them every year. Treat every number here as a snapshot and re-check it before you apply.
What the degree is supposed to teach
Behavioural science sits between psychology, economics and policy. If you are still deciding how it differs from psychology, read psychology vs behavioural science and what behavioural science is first. A serious master’s programme should give you three things: a grounding in judgement and decision making, training in experimental and quantitative methods, and a route into applied work such as public policy, product design or health. The balance between those three is where programmes diverge.
The methods component matters most. The field’s credibility depends on whether practitioners can test an intervention before they scale it. Hallsworth (2023) sets out a manifesto for applying the field, and its emphasis falls on the discipline of applied work. A programme that gives you a half-unit of statistics and a case-study seminar will leave you less ready for that work than one that makes you run a trial and analyse it.
Check three things in every syllabus. Does it teach experimental design in a required course? Does it include quantitative analysis beyond descriptive statistics? Does the dissertation require original data collection, or a literature review? Those three answers predict more about your first job than the programme’s brand.
Programmes compared
The table covers five programmes, four of which I checked on their own pages, with Warwick’s course listing consulted through search. It is not a survey of every master’s in the field.
| Programme | Length and format | Entry rule | Fee as published | Tilt |
|---|---|---|---|---|
| LSE MSc Behavioural Science | 12 months full-time; 24 months part-time (home students) | 2:1 or equivalent | £30,400 home, £32,000 overseas (2027/28 entry) | Psychology department; methods-heavy core |
| LSE Executive MSc Behavioural Science | 16-month modular part-time; three two-week intensive blocks in London | 2:1 plus three years of post-graduation work experience | £45,000 for home and overseas students (2027/28 entry) | Practitioners; research methods as a core component |
| University of Glasgow MSc Behavioural Science | 12 months full-time | 2.1 honours in any subject | £13,092 home and rest of UK; £31,515 international and EU (2027-28) | Business or Science Track, chosen after a shared foundation |
| University of Warwick MSc Behavioural and Economic Science | 12 months full-time | Not checked | Not verified on the official page, so omitted | Science or Economics track |
| UPenn Master of Behavioral and Decision Sciences | 1.5 years full-time or 2.5 years part-time; in person; nine course units | Not checked on this page | No tuition figure on the programme page | STEM-designated; decision science under Cristina Bicchieri |

Two details in the table need more explanation. First, the LSE Executive fee is high for a part-time programme, and the page says a £2,500 pre-registration fee is deducted from the total tuition figure. Second, Glasgow’s two tracks share a foundation, so you can choose the science route after starting. That flexibility is useful if you are not yet sure whether you want economics or psychology.
I did not include a fee for Warwick. The third-party listings I found disagree with each other, and the official course page did not give a figure I could verify. Leaving a number out is better than printing one that may be wrong.
UK options in more detail
The LSE full-time MSc is the most directly methods-focused option in the table. Its required courses include Foundations in Behavioural Science, Experimental Design and Methods, Quantitative Applications, and a dissertation worth one full unit. If your goal is an academic route or a research post, that required methods core is the main reason to choose it.
The Executive MSc at LSE solves a different problem. It is built for people who already work in the field and cannot leave a job for a year. Teaching happens in three two-week blocks at the Houghton Street campus, with remote study in between. The page states that no quantitative background is required, but it also lists research methods as a core component, so expect the statistics to be demanding. The three-year work requirement is a real filter, and the fee is the highest in this comparison.
Glasgow runs a 12-month MSc from the Adam Smith Business School and the School of Psychology and Neuroscience. Students must complete at least 60 credits from their chosen track’s school. For someone who wants to combine behavioural economics with a business context, the Business Track is the natural fit. For someone who wants a psychology foundation, the Science Track is. The entry requirement is a 2.1 in any subject, and the fee is far lower for home students. The international fee is still substantial.
Warwick’s MSc in Behavioural and Economic Science has a science track and an economics track. The economics track assumes a background in economics, so check the entry rules before you apply. I could not confirm the fee on the official page and have not guessed one.
I also saw Stirling and Kent listing MSc Behavioural Science programmes. I did not verify their official pages in time for this article, so they are not in the table. Do not treat their absence as a judgement.
US options
The most direct US match I could check is the Master of Behavioral and Decision Sciences at the University of Pennsylvania. It is an in-person programme, offered over three semesters full-time, with nine course units. The programme is STEM-designated, which can matter if you plan to work in the United States after graduation. Its founding director is Cristina Bicchieri, whose work on social norms gives the programme a clear social-science angle.
The deadlines are tight. For fall 2027 entry the priority deadline is 1 December 2026, and the regular deadline is 1 February 2027. The programme page does not show a tuition figure, so you will need the separate tuition and fees page before you compare costs.
If you search for a “master’s in behavioral science” in the US, expect to find programmes with that name in several different departments. Read the course list before you assume a programme matches the one described here.
Online and executive options
Online offers vary most in what they claim, so the checks matter more here. The LSE Executive MSc is the only executive programme in this comparison that I verified in full. For other online offers, the test is simple: find the course list, the assessment, and the named faculty, and check whether the dissertation requires original data. If any of those is missing from the official page, the programme may be a short course with a degree label.

How to choose
I would work through five questions in order.
- Do you have a statistics background? If not, choose a programme with a required methods course in the first term, and budget time for catching up before you start.
- What is the goal? An academic route needs a dissertation with original data and a strong methods core. A product or policy role needs applied projects and access to practitioners.
- Can you take a year out? A 12-month full-time programme is a large cost in salary as well as fees. In my view this is the question that decides most applications. Part-time formats such as LSE’s Executive MSc spread the cost, but that route requires three years of relevant work experience.
- What is the real total cost? Compare total tuition, living costs in the city, and any fees the page lists separately. LSE’s executive page, for example, says its fee does not cover fieldwork, travel or living costs in London.
- Does the programme name its faculty and its methods? A named director and a published course list are the minimum. Vague descriptions of “behavioural insights” without methods detail are a warning sign.
Once you have answered those five questions, the field narrows quickly. Most readers will end up with two or three programmes that fit.
Is it worth it?
The degree is worth it only if it leads to work you want. The jobs and salary picture is covered in behavioural science jobs, careers and salary, and I would read it before committing to a fee of £13,000 or £30,000. The most useful question is not “will a master’s help me?” but “which skills would I otherwise have to buy, and which of them does this programme teach?”
A master’s buys you three things: structured training in methods, a cohort and network, and a credential that helps when you apply for research posts. It does not buy you a job by itself. Candidates who already have quantitative experience, such as a data analyst working in marketing or an economist working in a regulator, often gain more from a targeted short course than from a full degree.
In my view
The most common mistake I see is choosing a programme by its brand and then discovering that its methods content is thin. A famous name on the transcript does not teach you to design a randomised trial. Check the syllabus first. Then check the fee. In that order, because the cheaper programme is only cheaper if it teaches what you need.
The field also needs people who can test claims rather than repeat them. That is a methods skill, and it is what the good programmes are really selling. Expect the next generation of programmes to put more weight on pre-registration, power analysis and open data, because the replication debates of the past decade have made those skills the price of entry for serious work. A programme that does not teach them in 2026 will look dated by 2030.
If you are weighing whether a degree or a targeted course fits your situation, start with the jobs guide and the course list, not with the marketing page.
Frequently asked questions
Which MSc Behavioural Science programme is the best?
There is no single best. For a methods-heavy academic route, the LSE full-time MSc has the most explicit methods core in this comparison. For a part-time route while you keep working, the LSE Executive MSc is built for that, but it requires three years of relevant work experience. For a shorter, lower-cost route to a UK degree, Glasgow’s 12-month programme has the lowest home fee of the full-time options in the table.
How much does a behavioral science master’s cost?
Fees in this comparison range from about £13,000 for home students at Glasgow to £45,000 at the LSE Executive MSc, both for 2027/28 entry. International fees are higher. Check the official page for your entry year, and add living costs, which are substantial in London.
Do I need a psychology or economics background?
Not always, but you should expect to need some quantitative skill. Entry rules in the table are mostly a 2:1 or 2.1 honours degree, and Glasgow accepts any subject. The LSE Executive MSc states that no quantitative background is required, while also requiring research methods as a core component. Plan to catch up in statistics before you start if your background is thin.
Is a master’s in behavioural science worth it compared with a short course?
It depends on the job you want. A master’s gives you structured methods training and a credential. A short course can be enough if you already have quantitative experience and need one specific skill, such as experiment design or behavioural analytics. The jobs guide sets out the roles and salary ranges that make the decision concrete.
