Internet• Considered a
major achievement of the human race, which brought us to information age
• Put’s the world knowledge at the end of your fingertips

Why?• Learn from
others• Most
problems has occurred to someone and already solved
• So you can stand on the shoulders of the giants!!

It could be • As simple as step by step
instructions to pair your phone with the car
• Controversial as “who is the best candidate for the president?”
• Confusing as “search for your symptoms”
• Complicated as “how best to market your product?”

Online Research• Goal is the truth• Finding facts, and
deriving conclusions
![Page 7: Doing Online Research](https://reader035.vdocument.in/reader035/viewer/2022070603/587006661a28ab427f8b6257/html5/thumbnails/7.jpg)
Four Parts• Get a feel for the Topic/ Search ( find
data, facts, and arguments) • Selects and refine facts you want to
base on • Make an argument • Write it Down
![Page 8: Doing Online Research](https://reader035.vdocument.in/reader035/viewer/2022070603/587006661a28ab427f8b6257/html5/thumbnails/8.jpg)
Get a Feel for the Topic
• Search (e.g. Google) • Authorities: Find few people who
writes, thinks about the same topics
• Look for few who disagrees • Read to get a high level idea • Talk to a friendly expert if you
know one, but fact check him/her too.
![Page 9: Doing Online Research](https://reader035.vdocument.in/reader035/viewer/2022070603/587006661a28ab427f8b6257/html5/thumbnails/9.jpg)
Search• Start with General keywords • Narrow down by adding more
details • Need to filter results (e.g.
promotional content), look for well known people and sources (e.g. Forbe’s, HBR, Wired)
• I found good content often come from blogs
• Good link’s sometime are down few pages

Tools of Trade• Initially Aim to
understand high level
• Take Notes ( with reference to sources)
• Use Mind Maps (e.g. Xmind, FreeMind)
• Use tables ( with features as rows and options as columns) to summarize the data

Follow a Topic• If interest is continuous, then
follow the topic!!• Setup Google alerts• Find sites that dedicated to the
topics• Find and follow experts (e.g. Blog,
tweets, LinkedIn. • Join groups, mailing lists • Attend a conference, Meetup
groups

Form an Opinion• To think
critically, you must have an opinion ( we call this the working hypothesis)
• Only trick is you need to be able to question and change it
![Page 13: Doing Online Research](https://reader035.vdocument.in/reader035/viewer/2022070603/587006661a28ab427f8b6257/html5/thumbnails/13.jpg)
Attack Your Opinion• Take an
example• Look at it
critically. E.g. Socrates Method
• Run it through a friend

How to Make a Claim?• Using logical arguments • Start with facts, and drive
conclusions • A => B, B=>C, then A=> C• When you write down this formally,
we call it a proof. When we write it down informally, we call it a argument
![Page 15: Doing Online Research](https://reader035.vdocument.in/reader035/viewer/2022070603/587006661a28ab427f8b6257/html5/thumbnails/15.jpg)
Know Your Logic • A=> B does not mean B=>A• Example ( existence of one) is not a
proof in general case • Proof by Authority is not proof

Use Common Sense • End of the day, it is the use of
common sense • Often it a matter of thinking how I
arrive at a given conclusion • However, what often leads us astray
is the facts

Argument is two parts: Facts and
Logic. Know which one is which

Each Fact need a Source• Sources come in many forms – Peer Reviewed Papers– Newspapers (L1)– Newspapers (L2)– Articles – Blogs – Social Media
![Page 20: Doing Online Research](https://reader035.vdocument.in/reader035/viewer/2022070603/587006661a28ab427f8b6257/html5/thumbnails/20.jpg)
Question Your Sources?• Sources come in many forms • Peer Reviewed Papers – have others confirmed
the finding?• Newspapers (L1) – has multiple sources has
confirmed it? Has the subject given chance to respond
• Newspapers (L2) - ??• Articles/ Blogs – is author an authority? Does
other authorities agree • Social Media – not a good source, only a link to
a source

Into the Shoes of Your Sources• What are their incentives? • What could be conflicts of
interests?• It is impossible to find an
unbiased opinion, but when there is bias, you need to look for multiple opinions

Write it Down• Write the logic in 2-3 pages• Follow and verify the argument • Make the difference between
conclusion and your opinions explicit
• Report any potential conflicts of interests
