Large-language models (LLMs) like GPT take every word you type as a fact.
If you write, “I led a team of ten engineers,” the model simply nods and builds on it — it has no way to peek at your résumé or ask for proof. That’s handy when your info is right, but dangerous when it isn’t, because the bot won’t push back.
1 | Why We Supply Shaky “Facts”
Blind-spot source
Everyday slip-up
Proof it’s real
We overrate our knowledge
Most people feel sure they can explain a bicycle pump — until they try. Over 40 % drew bikes that wouldn’t work. scotthyoung.com
Shared false memories
Millions “remember” Nelson Mandela dying in prison (he didn’t). Forbes
Self-promotion drift
70 % of job-seekers admit they have lied — or would lie — on a résumé. ResumeLab
These slips are harmless in conversation. Inside a chatbot, they harden into “truth” that shapes the entire reply.
2 | Hallucination vs. Blind Spot
Word
What happens
Who starts it?
Hallucination
The model invents facts that are nowhere in the prompt. Example: GPT-4 made up 28.6 % of medical citations in a 2024 test. JMIR
The model
Blind spot
We supply fuzzy or wrong info; the bot accepts it as real, no follow-up question.
The user
Both look equally confident on-screen, but only one begins with us.
3 | How Blind Spots Snowball
Job search — Claiming “five years of management” can make the bot craft a director-level résumé that sets you up for awkward interviews.
Healthcare — Stating “I’m allergic to penicillin” (when you’re unsure) steers advice toward costlier, less-effective drugs.
Finance — Inflated income in a budgeting prompt nudges you toward riskier investments.
Public image — Stable Diffusion already over-sexualizes or under-represents some groups across 32 professions; mix that with a vague prompt (“make me look powerful”) and an AI headshot can reinforce stereotypes. Nature
Deep-fake risk — Public deep-fake generators have been downloaded ~15 million times since late 2022, so an AI portrait built on shaky prompts can be remixed into scandals. Latest news & breaking headlines
4 | Why Cleaning Your Input Makes a Difference
4.1 Benefits
Sharper decisions — Advice based on verified facts is easier to follow and trust.
Reputation safety — A résumé or LinkedIn post built on fuzziness won’t crumble under a background check.
Bias brake — GPT-4 mirrors human thinking traps in nearly half of 18 classic bias tests; pruning your own bias keeps the echo small. INFORMS PubsOnline
Future-proofing — HR bots, loan analyzers, and medical triage tools will soon chain multiple LLM calls; one self-inflated skill today could misroute automated decisions tomorrow.
4.2 Consequences of Ignoring It
Bad calls — Acting on advice rooted in an exaggeration can waste money, time, or even harm health.
Snowballed misinformation — Your unverified claim can be quoted by another user or an automated system, spreading the error.
Loss of trust — Employers, clients, or friends who discover the gap may see every AI-assisted output from you as suspect.
Amplified bias — Unchecked personal bias feeds model bias, widening social stereotypes and inequities.
Legal & policy fallout — New AI accountability laws are emerging; providing misleading data could expose you to compliance or ethical issues.
5 | Five Habits to “Clean the Glass”
Habit
Prompt tweak
Why it works
Admit uncertainty
“I think I graduated in 2019 — could be 2020. Show both versions.”
The model hedges instead of anchoring to the wrong date.
Expose assumptions
“List the facts you’re relying on before you answer.”
Hidden gaps become visible for quick correction.
Self-reflection loop
“Now critique your last answer for errors.”
Iterative reflection cuts hallucinations >70 %. ACL Anthology
Multi-persona debate
“Give me a skeptic vs. believer debate on this claim.”
Persona battles shrink confirmation bias. arXiv
Ground with proof (RAG)
Attach a PDF, link, or reference photo.
Retrieval-augmented generation sharply lowers hallucination rates. arXiv
Quick Prompt Make-Over
Before
“I managed a $1 million budget. Write my executive bio.”
After
“My budget was between $ 600k and $1 million (records pending). Draft the bio and flag any line that assumes the exact figure.”
Small tweak, big save — the bot adds caveats instead of cementing a guess.
6 | The Evergreen Rule
“Garbage in, garbage out” first appeared in print in 1957 and is linked to IBM instructor George Fuechsel. The maxim is still true: your keystrokes are the AI’s raw data. Atlas Obscura
7 | Your 10-Minute Reality Audit
Copy the last prompt you sent to any AI tool.
Highlight each number, date, or self-claim you can’t prove in 30 seconds.
Tag each as uncertain or attach evidence.
Rerun the prompt and compare the answers.
You’ll watch the reflection sharpen in real time, and the advice will feel sturdier.
Chatbots aren’t crystal balls — they’re mirrors.
Clean the glass, and your decisions get clearer.

Nice post!
I have done RAG projects before and have some problems with accuracy.
Can you tell me some tricks of RAG for high accuracy?
Hi, for sure it is mostly with pre-processing and the model you choose, and I can help further on LinkedIn, feel free to ask me anything

Thanks, I will
