Whether you’re brand new to data science, have gotten your feet wet in this field or are an expert, you should know that working with data is all about generating knowledge. There are many handfuls of ways data can make things better. Consider these: Telling stories Exploring relationships Backing up decisions Finding patterns Judging experiments Answering questions When anaylyzing data, the goal is to turn information into insights and in order to create insights about the right things, we must ask the right questions. Practicing any of the above well would require one to have many “hard skills” like coding, visualization, data cleaning, math modelling, graph interpretations, etc. What is far less talked about are the “soft skills” for making data useful, and of all the skills that a successful student or expert of data science needs to have, . All data analysts and scientists should embrace critical thinking as a key skill and capability. critical thinking is definitely at the top of that list I’ve researched and investigated critical thinking for myself to build my own skills for data analysis: What is it, why is it important, what are the benefits, when is it required and how can we get better at it?

How Can We Improve Critical Thinking? The essence of the independent mind lies not in what it thinks, but in how it thinks” — Christopher Hitchens The good news is that thinking critically is a learned skill, which can be cultivated in anyone. You simply are not born with innate critical thinking skills. That said, if you want to be a good critical thinker, you need to remember that it’s all about practice. Like any habit, there are certain muscles you need to flex over time. Below, you’ll find 5 ways to improve your everyday critical thinking. Focusing on these will put you on the path to becoming an exceptional critical thinker. 1. Identification The first step in the critical thinking process is to identify the situation or problem. Once you have a clear picture of that, and the factors that may influence it, you can begin to dive deeper into it and its potential solutions. When faced with a new situation, question or scenario, stop to take a mental picture of how things are stacked up. How to Improve: 2. Ask Questions “It is better to debate a question without settling it than to settle a question without debating it” — Joseph Joubert Learn to question everything. It’s very easy to accept things at face value, but that’s a sign of a lazy mind. You can start by asking the following questions: How to Improve: What do you already know? How do you know that? What seems to be the reason for this happening? What are you trying to prove, disprove, demonstrate, critique, support? What are you overlooking? You should continually go back to these basic questions you asked when you set out to solve the problem. These types of questions urge you to get right to the core of a problem, examining it for simple solutions before assuming its complexities. 3. Be Aware of Your Mental Process Being a good critical thinker requires you to accept that you have biases. Although even the best critical thinkers will never be entirely bias-free, you need to learn to look out for them. Make a habit of asking yourself what you’re assuming and why you’re assuming that, and check for things like stereotyping. How to Improve: Becoming more mindful of your own biases is the first step to rewriting these parts of your thinking. 4. Adjust Your Perspective Good critical thinkers do their best to be neutral with respect to their own beliefs and thoughts, spotting biases and prejudices and then correcting them. Think of yourself as a judge. You have to evaluate both sides of an argument, but you also need to keep in mind the biases each side may possess. How to Improve: When evaluating information, ask yourself theses questions: Who will this benefit? Does the source have an agenda? Is the source ignoring, overlooking or leaving out information? Is this source using unnecessary language to change an audience’s mind? 5. Establish Foresight Critical thinking is heavily dependent on problem-solving. An effective critical thinker will have the foresight to anticipate roadblocks and negative outcomes. You’ll be able to make the right decisions if you can already see the consequences down the line. Making a pro and con list is a great way to boost foresight, making you better at predicting outcomes. The more you do this, the less work you need to put into your attempted predictions each time. How to Improve: 6. Be an Independent Thinker “Too often we enjoy the comfort of opinion without the discomfort of thought” — JFK Don’t get hung up in research, reading, others’ opinions that you forget to think for yourself. You must learn to think for yourself and take ownership of your own values, beliefs, judgments, and decisions. One of the best ways to avoid mental laziness is to practice the 15-minute rule — a process you can apply when you get stuck: How to Improve: When you’re presented with a problem you don’t immediately know the answer to, ask if you have even a small amount of confidence to solve it on your own If yes, then spend 15 minutes trying to solve the problem Document each step of your process If you still haven’t solved the problem after 15 minutes, get help (from a person or Google). Over time, this process will help you build your critical thinking skills and self-reliance. Conclusion I hope you found this article resourceful and are able to use some of it to help you think more critically in your career and your life. If you approach critical thinking skills as a process to follow, you’ll consistently heighten your thought process and when utilized regularly, it will become a habit and improve your critical thinking skills over time. learning to think critically is a never-ending journey, there is always more to learn, assess and improve.
