Dhaliwal also makes a few early generalizations, and he thought that Andreas might have a lung infection or an autoimmune problem.
There wasn’t enough data to offer any sort of reliable conclusion, though, and really Dhaliwal was just gathering information.
The community member may conduct a survey (through mail, over the phone, in person) to get answers to questions about recycling.
Finally, the community member may ask leaders from other neighborhoods what their recycling pick-up frequency is.3) Construct a hypothesis: After investigating the issue, the community member will develop a hypothesis.
The scientific method beings with a question (perhaps stemming from an existing problem).
For example, a community member may notice the entire neighborhood has overflowing recycling bins on recycling pick-up day.An emergency medicine physician, Dhaliwal is one of the leaders in a field known as clinical reasoning, a type of applied problem solving.In recent years, Dhaliwal has mapped out a better way to solve thorny issues, and he believes that his problem solving approach can be applied to just about any field from knitting to chemistry."2) Do background research: The community member may start to ask neighbors and other community members what their experiences are with recycling.Do they feel adequately supported by the frequency of recycling pick-ups?’s free newsletters."data-newsletterpromo-image="https://static.scientificamerican.com/sciam/cache/file/458BF87F-514B-44EE-B87F5D531772CF83_source.png"data-newsletterpromo-button-text="Sign Up"data-newsletterpromo-button-link="https:// origincode=2018_sciam_Article Promo_Newsletter Sign Up"name="article Body" itemprop="article Body"For Gurpreet Dhaliwal, just about every decision is a potential opportunity for effective problem solving. Should Dhaliwal write his research paper today or next week?"We all do problem solving all day long," Dhaliwal told me.Since recycling pick-up only happens on Mondays, the community member may...Since recycling pick-up only happens on Mondays, the community member may ask: Do we need an additional recycling pick-up day to support the amount of recycled material in our community?"Problem solving is part craft and part science, " Dhaliwal says, a type of "matching exercise." To get a sense of Dhaliwal’s approach, I once watched him solve a perplexing case.
