Automated Thematic Analysis and the Death of the Literature Review?
If you’re an academic, you know the drill. Step one: get excited about your research topic. Step two: immediately drown in 200+ papers you need to read before you can even start writing.
The literature review is an essential part of research - but if we’re honest, it’s also a gruelling, time-consuming, and often overwhelming process.
Now, AI tools claim they can do it for you. They promise to scan thousands of papers in minutes, summarise the key themes, and spit out a neatly packaged overview of your field.
Sounds tempting. But we already know the problem. AI doesn’t understand your research! (I sound like a broken record at this stage, don’t I?)
We know it doesn’t think. It doesn’t weigh evidence. It doesn’t care about nuance. It just predicts patterns and assembles words accordingly - which means if you let AI do your literature review, you’re not just skipping the hard part…
You’re skipping the part that actually makes you a researcher.
Why Do a Literature Review Anyway? Can’t You Just Skip to the Good Stuff?
If you’ve ever groaned at the thought of reviewing yet another paper, you’re not alone. BUT (and read this next part in your supervisor’s voice):
A literature review isn’t just about proving you’ve done your homework. It’s about making sure you’re not wasting your time.
Imagine spending two years on a research project only to realise someone already did the exact same study… five years ago.
A good literature review:
Shows you what’s been done (so you don’t repeat it).
Reveals where the gaps are (so you know where to focus).
Helps you learn from past research (so you don’t make the same mistakes).
It’s not just a box to check, it’s how you develop real expertise in your field before trying to push it forward.
So yeah, it’s important. But does that mean you need to spend months slogging through journal articles manually?
Absolutely not.
But if we’re going to start talking about that, we need to first talk about:
Why You Shouldn’t Let AI Do Your Literature Review for You
AI tools like ChatGPT, Elicit, and Scite claim they can scan thousands of papers, extract themes, and summarise key findings. But before you hand over your reading list, consider this:
1. AI Only Predicts. It Doesn’t Understand
AI isn’t reading papers the way you do. It doesn’t engage with theory, methodology, or nuance. It just predicts what words should go together based on past patterns.
That means:
AI summaries miss important caveats or limitations.
It prioritises papers based on popularity, not relevance.
And worst of all? AI hallucinates citations - completely making up studies that don’t exist.
You wouldn’t build a research project on bad data, so why build it on a bad summary of good data?
2. You Lose the Critical Thinking Process
The act of reading and synthesising research is what turns you from someone with access to papers into someone who actually understands the field.
AI can summarise findings, but it won’t tell you which study was more rigorous.
AI can highlight themes, but it won’t explain why those themes matter.
AI can give you a list of citations, but it won’t challenge you to think about contradictions in the literature.
Skipping the literature review means skipping the process that makes you an expert.
3. AI Gives You the ‘What’, Not the ‘Why’
AI-generated literature reviews tend to spit out lists of topics without actually explaining how they connect. But research isn’t just about what’s been studied - it’s about why those studies matter and how they build on each other.
If your literature review reads like a list of random facts with no real argument, congratulations—you’ve successfully outsourced your thinking to a machine.
So What’s the Alternative? A Smarter Way to Review Literature (Without the Laziness)
If AI can’t be trusted to write your literature review, does that mean you have to spend months manually reading every paper yourself?
Not quite.
This seems like a good time to talk about Leximancer.
What’s Different About Leximancer?
Unlike AI, Leximancer doesn’t generate text. It extracts themes from research papers and maps how they connect.
Here’s why that matters:
✔️ It reads for you - but doesn’t think for you.
Leximancer processes massive amounts of text and identifies key themes without hallucinating citations or fabricating insights.
✔️ It shows relationships - so you can see the big picture.
Instead of just listing topics, Leximancer maps out how concepts are connected, helping you quickly spot patterns and knowledge gaps.
✔️ It saves you time - without skipping the learning process.
Leximancer gives you a high-level overview of your field in minutes, so you know where to focus your deeper reading—instead of wasting time skimming irrelevant papers.
It’s not AI doing the thinking for you. It’s machine learning helping you think faster and smarter.
The Future of Literature Reviews: Smarter, Not Lazier
AI isn’t going to kill the literature review, but machine learning is going to change it.
The old method? Reading hundreds of papers blindly, hoping to identify themes manually.
The smarter method? Using machine learning to map the research landscape and focusing your reading where it matters most.
AI won’t make you an expert.
But Leximancer can help you become one faster.
So the question isn’t: Should AI replace literature reviews?
The smart question is: Are you still doing them the slow way?
