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.
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 third phase of problem solving is “carrying out the plan.” This is a matter of doing—and vetting: “Can you prove that it is correct?
” The final phase for Polya is “looking back.” Or learning from the solution: People should "consolidate their knowledge.” While Dhaliwal broadly follows this four-step method, he stresses that procedures are not enough.
Dhaliwal had a few strong pieces of evidence that supported the theory including some odd-looking red blood cells.
But Dhaliwal wasn't comfortable with the level of proof.
If we’re more aware of how we approach an issue, we are better able to resolve the issue.
This idea explains why people who talk to themselves are more effective at problem solving. As for Dhaliwal, he had yet another problem to solve after his diagnosis of Andreas: Should he take an Uber to the airport? After a little thought, Dhaliwal decided on an Uber.
