Which is more accurate and reliable: Wikipedia or Quora?

För vilka frågor är Wikipedia bäst och när är Quora bäst? Jag vill gärna tänka att tankesatt kan bli bäst inom sitt område, nämligen hur man ska komma ur sitt databeroende.

Answer by Steven Walling:

The answer to this question depends on type of knowledge you're looking for. For context, I've written more than 200 Wikipedia articles and almost 350 Quora answers, so based on my comparisons between the two:

  • Quora is more reliable and accurate for getting at the truth about subjects that are best understood based on personal experience and expertise. When I want to know what it was like to be in Auschwitz and be a subject of human experimentation, you cannot beat reading accounts by Holocaust survivor Eva Kor. This doesn't just apply to famous people either. When it comes to the details about NASA and International Space Station operations, getting the information direct from someone like NASA engineer/instructor Robert Frost is so much better than a Wikipedia article written based on dry news reports. Quora has real experts writing in so many fields relevant to our lives, from police officers to physicists. This is only going to grow over time as we fill out the diversity of the Quora Topic Network.
  • Wikipedia is better at being reliable for objective facts that can be verified with other sources. On Quora, you are encouraged to use citations and sources, but on Wikipedia it's required. As an encyclopedia, Wikipedia's process is weighted heavily toward things that can be confirmed by many published sources as fact.

We can take a relevant example and break this down. Measles is an important topic, due to the 2015 Vaccination Debate and Measles Outbreak in the United States. Quora tells me a lot about issues such as why many parents choose not to vaccinate. Even pretty scientific aspects like What makes measles so contagious? are answered thoughtfully by experts on Quora. However, when I want to know the statistics on regional infection rates, I turn to Wikipedia because it aggregates facts from many reliable sources.

I am 25 and very lazy. What should I do?

Det här verkar vara bra råd. Jag kan känna igen mig sjäv i delar av beskrivningen och jag tror mig se många av mina elever. Hoppas ni får nytta v tipsen i den här texten från Quora.

Answer by Mateesh Bhave:

I am going to tell you one simple truth. No matter how many motivational videos you watch or self help books you read, it is not going to help you. Not one bit.

For normal people it might work, but for us it will motivate us for an hour hardly and then it all goes away and we are back to square one. Läs mer…

What, programming-wise, would be most useful to learn in a few months?

Answer by Pushparaj Adigopula:


You don't lose anything if you don't learn .NET, Python, Java or Ruby. But without JavaScript you cannot make your mark as a programmer as web applications are expanding their scope beyond web applications. (eg. Metro apps and apps for ChromeOS etc. )

With Node.js, JavaScript has grown to accommodate a full stack from frontend to backend and even full length database systems.

You can develop a full length web application using only JavaScript:

What can I start today that will benefit me for a lifetime?

Bra om att utveckla sig själv. Mitt förslag är att du skriver på tankesatt!

Answer by Santhosh Komaraju:

Every week day the time allocation goes something like this:

  • 8 hrs (at work / at school /at business)
  • 8 hrs (sleep)
  • 1 – 2 hrs (commute to work)
  • 1 hr (Dinner, Breakfast, lunch)
  • 1 hr Rest room activities all day long
  • 2 hrs (Miscellaneous activities / Family time )

As  you see whatever life style you are leading, 22 hours are now gone.  From remaining 2 hours, if you take 50% out, which is 1 hour. Dedicate just  this 1 hour completely for yourself. And when I say for yourself,  for  your inner self. No social websites, No internet, No cell phone use, No  Television. Cut out all these and just dedicate this 1 hour completely  for your inner self. Here is what you can do:

  1. Read a book / article.
  2. Write your thoughts or blog about anything you are interested in. I strongly suggest to share your posts regularly with like-minded people or communities as you write new ones to get healthy feedback and at the same time recieve new information. This further would give you a boost to progress towards healthy writing.
  3. If you have any hobby start working on personal home projects.
  4. Write personal journal (just something which indicates your daily experiences, dreams , life goals, ideas – no matter how small they are write it down)
  5. Get involved in some charitable work.
  6. Volunteer on any kind of activity online and offsite which might help anyone.
  7. Watch any documentary which is educational in nature.
  8. Do any kind of spiritual activity – Meditation, Yoga , Pranayama, Prayer etc.
  9. Just sit & Relax and introspect about your life.
  10. Do any physical activity – Exercise, Cardio, Play indoor/outdoor sport (not video games)                           

Most  important thing is that you do this just for yourself without any  expectations. Amazing things can come out with just this 1 hour of total  conscious efforts which you have not imagined prior. Hidden attributes  can come out, Never seen talents can come out from you. All because of  spending just 1 hour of your day's time. What you are doing here is  going deep inside yourself to see what's inside. And once you find it,  you bring it out and spend 1 hr of conscious efforts on it without any  expectations. Leave it to the destiny on what it might become in future.

How can I come to like learning and reading instead of doing mindless things?

Hur man går från dataspelande till att läsa fler böcker.

Answer by Brandon Lee:

I wondered this for a very long time as a teenager, back when I regularly spent all-nighters gaming, and ironically, it was gaming that gave me the insight to overcome my psychological barriers.

Learning/reading are mentally demanding tasks and that's the main struggle, I remember thinking, "Man, I should really read instead of aimlessly burning the next 5 hours on the computer. Uhhhhh but that sounds like work… Hello computer!"

But then I noticed, whenever I encountered a new, balanced, and challenging game (Desktop TD — pictured below — and Gemcraft come to mind), my brain sharpened up, fully engaged, and became alert in order to beat that level/stage/wave.

I'd all of a sudden have this stubborn diligence to test and perfect my strategy, even if it took an hour to figure it out.

Where the heck did all that motivation and focus come from!? I reflected on that and noticed:

  1. There was a clear reward/benefit. Upgrades, advancing, and the ability to tackle the next level — progress feels good! Which led to
  2. A clear objective. Beat the level — it's obvious when I have/haven't made it, it's also encouraging when I know I'm getting very close!
  3. There was a sense of challenge — not a cakewalk (boring), but not impossible (discouraging)

And then I recollected on the reasons why I  had picked up books in the past and had read with a similar alertness, focus, and level of engagement:

  1. Often it was after someone told me what they were able to accomplish because of what they read the book (clear reward/benefit).
  2. And upon asking for more details, they would elaborate and break down the principles that fueled their accomplishments (clear objective).
  3. Often, the book was a topic I hadn't already mastered (so it wasn't too familiar or boring), but wasn't something I was completely clueless about (way above my head).

In other words, I needed to be able to understand, "Oh if I read this book, this is what I will get out of it and this is how it might affect me."

That's why I hate it when someone recommends me a book by simply saying "This book is good, you should read it." Uh. Why? Unless you're someone I'm studying or greatly admire, that recommendation means squat to me.

But if you tell me, "You should read this book, I was able to understand XYZ and  was able to accomplish A, B, and C because of it!! It's changed how I see in so many other ways." Holy crap, your book will jump up to the top (or near the top) of my list.

Here's a great example of what I just described:
Brandon Lee's answer to I'm 17. What books would you recommend to me to improve myself?

In my answer, each "nutshell" that I provided, I explain "this is what you will learn and this is how it's relevant to your life." And for a few of them, I linked to outlines in case my nutshell didn't suffice. You can compare and contrast my answer with all the other answers and see a distinct difference.

So all that to say, if you want to be more "motivated" to read a book, either read reviews that explain the basic takeaways, talk to someone who has read it, or try to find an outline of the book. Take the time understand what the book actually has to offer you, otherwise you'll just be left with the nagging feeling that you should be reading, but never actually do it.

How can I come to like learning and reading instead of doing mindless things?

Why the modern world is bad for your brain

Why the modern world is bad for your brain är en artikel i the Guardian som behandlar hur det moderna samhället påverkar våra hjärnor på ett synnerligen negativt sätt. Strömmen av information och stimuli ger ökade nivåer av kortisol, adrenalin och dopamin. Vårt fladdrande på nätet stimulerar ett nyhetscentra i prefrontala cortex att ständigt vilja ha mer nyheter. Man kan likna det vid ett drogberoende. Som förälder till en tioåring och en fjortonåring känner jag igen detta i alla konflikter som uppstår när vi vill begränsa deras telefonerande. jag är allvarligt oroad att de förstör sin framtid.

Nedanstående stycke sammanfattar det hela på ett tankeväckande sätt.

Multitasking has been found to increase the production of the stress hormone cortisol as well as the fight-or-flight hormone adrenaline, which can overstimulate your brain and cause mental fog or scrambled thinking. Multitasking creates a dopamine-addiction feedback loop, effectively rewarding the brain for losing focus and for constantly searching for external stimulation. To make matters worse, the prefrontal cortex has a novelty bias, meaning that its attention can be easily hijacked by something new – the proverbial shiny objects we use to entice infants, puppies, and kittens. The irony here for those of us who are trying to focus amid competing activities is clear: the very brain region we need to rely on for staying on task is easily distracted. We answer the phone, look up something on the internet, check our email, send an SMS, and each of these things tweaks the novelty- seeking, reward-seeking centres of the brain, causing a burst of endogenous opioids (no wonder it feels so good!), all to the detriment of our staying on task. It is the ultimate empty-caloried brain candy. Instead of reaping the big rewards that come from sustained, focused effort, we instead reap empty rewards from completing a thousand little sugar-coated tasks.
