Better science makes for better decisions

Better science does not make decisions easier

Forty years of development in the science and technology of estimating and quantifying risk, of understanding of human behaviour and human rationale has made decision makers more informed. We are in a much better position now, than forty years ago in estimating probabilities, consequences, and damages, and in estimating and dealing with the associated uncertainties in an organised way. This did...

Better decisions through science: exercise testing scores.

Statistical tools can be used to create scores for assisting in the diagnosis of coronary artery disease and assessing prognosis. General practitioners and internists frequently function as gatekeepers, deciding which patients must be referred to the cardiologist. Therefore, they need to use the basic tools they have available (ie, history, physical examination and the exercise test) in an opti...

How SmithKline Beecham makes better resource-allocation decisions.

Major resource-allocation decisions are never easy. For a pharmaceuticals company like SmithKline Beecham, the problem is this: How do you make good decisions in a high-risk, technically complex business when the information you need to make those decisions comes largely from the project champions who are competing against one another for resources? In 1993, the company experimented with ways o...

WhenWalking Makes Perception Better

When we move, the visual world moves toward us. That is, self-motion normally produces visual signals (flow) that tell us about our own motion. But these signals are distorted by our motion: Visual flow actually appears slower while we are moving than it does when we are stationary and our surroundings move past us. Although for many years these kinds of distortions have been interpreted as a s...
