As noted earlier, the use and application of these tools to any issue demands some (a very little) learning along with some (a fair bit of) 'unlearning' as a prerequisite. It should be observed that:
i) The learning and the 'unlearning' will have to proceed in tandem;
ii) 'Unlearning' is quite considerably more difficult to do than learning. Some people are never able to unlearn. This generally means that those people will never be able learn the specific things that are needed to apply these tools to practical issues.
