The Pareto Principle: Work Smarter, Not Harder
Understanding the 80/20 Rule in Your Studies
You might have thought that doing well means doing loads of extra work – this is a mistake lots of students make! Actually just spending tons more time studying is not the most useful way for you to do well, and the reason can be explained by looking at the work of a 19th century economist. You might have heard of the Pareto principle before – if you haven’t, you’ve been missing out!

Vilfredo Pareto was an economist who noted that 80% of the land was owned by only 20% of the people; this important 20 % were the vital few who held much sway in society. Joseph M. Juran was a management consultant who took this one step further and suggested that in much of human life 20% of our actions determine 80% of the results. This is true in business, and much of nature shows this phenomenon too. Think about your work…does this apply to you?

One day you sit down to work on a subject that is important to you. At the end of your work, you look at the clock. Five hours has passed and you feel happy that you have done so much work. But looking at how much you actually have done you start to feel sad. Five hours and you’ve only really produced a small amount of work. How did this happen? Well, you might have got a little bit distracted, checked facebook, twitter, Instagram, snapchat, email, WhatsApp, Tumblr and so on. Maybe you had to go grab some food halfway through – totally normal! Plus you might have helped your brother with his homework or your mum with some quick chores. In reality how much of your study time was spent studying? Maybe 20%?
And it isn’t just distractions that cause a problem. Think about all the times you’ve studied before – I bet you used loads of different methods. Whether it’s sitting down learning words from the textbook, or watching TED talks, researching on Wikipedia or doing past paper exams, there are all sorts of ways of studying. But all studying isn’t equal. Some studying is really efficient, like work through actual questions. Other studying, like spending an hour on Wikipedia looking at ‘related’ articles isn’t that great. In fact, if you look at what you do when you’re studying I bet you’ll notice a pattern. About 80% of your work is pretty pointless, whether it’s reading stuff you already know, or watching things you don’t need to. In fact, for most students, 20% of the work produces 80% of the results – just as the Pareto principle predicts!
Applying the Pareto Principle to Your Study Habits
So what can you do about it? Well here’s the winning technique:
- Make a to-do list
- Order it starting with the most important
- Block off a chunk of your day every day (maybe 2 hours?) to work on your most important thing
- Be specific about your tasks and always keep focused on your most important task
Example Application
Step 1: Create a To-Do List

- Math homework
- Prepare for a French test
- Write a Coursework Essay (on the Roman Empire)
Step 2: Prioritize Your Tasks
Reorder it:
- Write a Coursework Essay (on the Roman Empire)
- Prepare for a French test
- Math homework
Step 3: Block Off Dedicated Study Time
Note to self: 1600 – 1800 work on coursework each day until done.
Step 4: Focus on the Vital Few
Choose the most important task within the whole piece of work and always make sure you’re working on that because that task is the vital 20 percent.
Now you know how to be efficient, go and choose one task – the most important task – and get started!

Why Lanterna?
The Pareto Principle, also known as the 80/20 rule, suggests that roughly 80% of effects come from 20% of causes. In IB study, this means that a small percentage of your study efforts (the 'vital 20%') will likely produce the majority of your results. The key is to identify and focus on these high-impact tasks rather than just spending more time studying inefficiently.
Many students make the mistake of thinking more hours automatically equals better grades. However, if those hours are filled with distractions, inefficient methods (like passively re-reading notes), or low-impact tasks, the actual productive study time can be minimal. The Pareto Principle highlights that quality and focus on the right tasks are far more important than sheer quantity of time spent.
Identifying your vital 20% involves understanding what truly drives your grades. This often includes active recall, practicing past paper questions, understanding core concepts, and working on high-stakes assignments like IAs and EEs. It's about focusing on tasks that directly test your knowledge and application, rather than passive activities like endlessly watching related videos or reading already understood material.
To apply the Pareto Principle, start by making a detailed to-do list for your studies. Then, critically order these tasks by importance, identifying the single most impactful item. Dedicate a specific, uninterrupted block of time each day (e.g., 2 hours) to focus solely on this most important task, ensuring you're specific about what you aim to achieve within that time. This structured approach helps you consistently tackle your 'vital 20%'.
Lanterna's expert tutors, many of whom scored 40+ in the IB or have extensive teaching/examiner experience, are skilled at helping students identify their most impactful study areas.
