By skyforbes What is GIGO?
GIGO stands for "Garbage In, Garbage Out" – a fundamental principle stating that flawed, incomplete, or poor-quality input will inevitably produce flawed, incomplete, or poor-quality output. Originally from computer science, this concept now applies to virtually every domain where information is processed or transformed.
7 Prompts That Demonstrate GIGO in Action
1. AI Prompting: Vague vs. Specific
Garbage In:
"Write something about dogs."
What You Get: A generic, unfocused paragraph that could be about anything from dog breeds to dog training to dog history.
Quality In:
"Write a 200-word guide for first-time dog owners on how to choose between adopting a puppy vs. an adult dog, focusing on time commitment and temperament differences."
What You Get: A targeted, useful guide that actually answers a specific question with actionable information.
2. Data Analysis: Incomplete Data Sets
Garbage In:
Analyzing customer satisfaction with only responses from people who rated 5 stars (ignoring all other feedback).
What You Get: A falsely positive picture suggesting 100% satisfaction when reality might be very different.
Quality In:
Collecting feedback from all customers regardless of rating, including follow-up with non-respondents.
What You Get: Accurate insights into actual satisfaction levels and specific areas needing improvement.
3. Programming: Assumptions vs. Validation
Garbage In:
python
def calculate_average(numbers):
return sum(numbers) / len(numbers)
Running this with an empty list crashes your program.
Quality In:
python
def calculate_average(numbers):
if not numbers:
return 0
return sum(numbers) / len(numbers)
Input is validated before processing, preventing errors.
4. Research: Biased Sources
Garbage In:
Writing a report on climate change using only blog posts from energy companies with vested interests.
What You Get: A skewed perspective that doesn't reflect scientific consensus.
Quality In:
Using peer-reviewed studies, data from scientific organizations, and diverse expert opinions.
What You Get: A balanced, credible analysis that withstands scrutiny.
5. Decision Making: Emotional vs. Factual
Garbage In:
Deciding to invest in a stock because "everyone is talking about it" and it "feels like a winner."
What You Get: High risk of loss based on hype rather than fundamentals.
Quality In:
Analyzing financial statements, market trends, competitive position, and consulting with financial advisors.
What You Get: An informed decision based on actual data and risk assessment.
6. Communication: Unclear Instructions
Garbage In:
"Hey team, we need to fix the thing by sometime soon-ish. You know what I mean."
What You Get: Confusion, missed deadlines, wrong priorities, and frustrated team members.
Quality In:
"Team, please fix the login authentication bug (ticket #247) by Friday 5 PM. Priority: High. John will lead, Sarah will test."
What You Get: Clear action items, accountability, and timely completion.
7. Learning: Passive vs. Active Engagement
Garbage In:
Watching a tutorial video while scrolling social media and hoping knowledge will osmose into your brain.
What You Get: Minimal retention and no practical skills.
Quality In:
Watching the tutorial, taking notes, pausing to try examples yourself, and building a small project to apply the concepts.
What You Get: Deep understanding and usable skills that stick.
The Key Takeaway
GIGO isn't just about avoiding bad inputs, but it's about being intentional with what you feed into any process. Whether you're:
– Prompting an AI
– Writing code
– Making decisions
– Learning new skills
– Communicating with others
The effort you put into crafting quality input directly determines the value of what you get out.
Note: You can't optimize your way out of fundamentally poor inputs. Start with quality, and quality will follow.
