Look at the facts not the opinion about the facts. Anyone holding themselves out as an expert has, a very deep but narrow knowledge base that is rarely universally applicable. Fundamentally, listening to opinions rarely give useful insight. Often, it assumes looking backward but does not apply to the current situation. Global commerce, trade (and trade wars) tariffs, flexible manufacturing, and global markets, along with technological innovation and automation create significant pressures against inflation, regardless of employment levels. These are the set of facts to be considered, not an assumed economic model where few people understand the actual inputs from 50 years ago.Another example looks at revenue projections based on historical business models. But what happens when those business models are changing? We discussed the example of the metamorphosis from Blockbuster to Netflix where a fundamental change in the business model made revenue projections from the historical model meaningless. Then, Netflix had to change their business model again to one of the original production and international expansion – once again obviating existing models for revenue. Facts are what happened. Specific and verifiable. Knowledge is the appropriate combination of facts. Knowledge comes from understanding the facts that matter. Wisdom is the insight that leads to prediction. At its core, any investment strategy predicts the future. To predict the future effectively one needs the wisdom to grasp what will happen. Of course, this cannot be known, and there are many random events that can affect the future (see Anti-fragile and Fooled by Randomness by Naseem Taleb), and uncertainty should always be factored into any investment decisions or predictions.
