Most confident Si-types seem to have a positive outlook toward their own abilities to accomplish things. They seem to accumulate a wealth of precedents, examples and or approaches that can be applied to most situations; with routine matters, they're superb. However, they frequently underestimate or fail to see the scope, implications and consequences of new undertakings. They can be rather impetuous and frequently need the resources to do redo the same project because they will often try to take risky shortcuts to save resources or increase potential efficiencies. Their can-do attitudes is linked to an apparent inability to accurately predict unprecedented consequences; when they finally do see the precipices, they often crash and need to be rebooted.
