Think of knowledge as a jigsaw puzzle; each piece is a fact, and when put together, it forms a complete picture. To be considered as knowledge, a piece of information must be justified (backed by evidence), true (accurate), and believed (accepted). Fun fact: this is called the JTB theory of knowledge! 🧩

Real-World Example: You know that Earth is spherical, right? That's because it's been observed and verified by scientists (justification), it's a fact (true), and you believe it.

Yes, like tools in a toolbox, different types of knowledge serve different purposes. Practical knowledge (how to ride a bike) is handy for daily tasks, while theoretical knowledge (E=mc²) is essential for scientific developments. So, usefulness varies based on context! 🧰

Real-World Example: Knowing how to perform CPR (practical knowledge) can save lives during emergencies, while understanding astrophysics (theoretical knowledge) could aid space exploration!

The source of knowledge (trustworthy or not), the methodology used to gather it (rigorous or sloppy), and the presence of bias (objective or subjective) can influence its reliability. Always fact-check, my friend! 🔍

Real-World Example: Scientific journals are usually reliable because they involve peer-review (good source), follow strict research methods, and aim for objectivity.

We become suspicious when a claim lacks evidence, contradicts known facts, comes from an unreliable source, or is influenced by bias. Doubt is a critical thinking tool - use it wisely! 👀

Real-World Example: If someone says, "I can fly like a bird without any tools!" You'd likely doubt it because it contradicts known facts (humans can't fly naturally).

Good evidence is robust (can withstand scrutiny), relevant (directly supports the claim), and comes from reliable sources. Without it, a claim is like a kite without a string, floating aimlessly! 🪁

Real-World Example: If you claim climate change is real, solid evidence might be rising global temperatures over the past century, sourced from reputable scientific organizations.
