As well as the obvious physical changes, Extremis also affected Stark mentally, allowing him to process information extraordinarily quickly, on a subconscious level, to help him better cope with the direct technological link he now possessed to his armor (even as his standard thought processes remained at a human norm). As a result, his brain, taking in more information than he could consciously process, began to sublimate it into his unconscious mind, causing Stark to experience occasional hallucinations of particularly relevant information, manifesting as people whose deaths he felt personally responsible for—such as Captain America or Happy Hogan —making him aware of facts that he had noted subconsciously while not recognizing their relevance or existence on a conscious level (such as that a member of the Initiative had lied about his powers or that Maya Hansen was actually alive after her death was faked). Doc Samson speculated that the hallucinations appeared because the excess information was filtered into the same place Stark subconsciously stored his guilt to stop himself facing it. 
With a higher propensity to invest comes the debt-driven crisis that Minsky predicted, and which we experienced in 2008. However, something that Minsky did not predict, but which did happen in the real world, also occurs in this model: the crisis is preceded by a period of apparent economic tranquillity that superficially looks the same as the transition to equilibrium in the good outcome. Before the crisis begins, there is a period of diminishing volatility in unemployment, as shown in Figure 4: the cycles in employment (and wages share) diminish, and at a faster rate than the convergence to equilibrium in the good outcome shown in Figure 3.
