Assumption is a lazy man's approach to making decisions, it's always better you stay in the current when stating facts or making decisions. Some Craftsmen and professionals who brings bills of quantity or cost implications of for a contract agreement most times makes this mistake by using old prices and thinking things are still the same in the market, only to be surprised by a current hike in price. This very mistake could've been avoided only if they went the extra-mile to validate the pricings with proper research before presentation. This have made a lot of them to loose in contracts as some times, they use their own workmanship to cover up for their mistakes, unless their employer is very considerate.
In P2P trading, assuming that your funds are in your account simply because the buyer confirmed sending it, or you got a credit alert has stripped lots of people their precious coins. You need to log into your app preferably and check your transactions history to be sure the funds are there or use USSD to demand your account balance from the bank for validation. You can even buy little units of airtime to see how the funds decreases.
Issues span between friends when they assume and misinterpret the actions or intent of others, or make conclusions from hearsay, accepting it as a valid truth without questioning, or validating from the person in question of the authenticity of such information. A simple validation of facts would spur better understanding among friends.
In the office when given instructions, demand clarity instead of assuming that things should go a certain way, these assumptions can be very costly sometimes and lead to queries, pay cuts and even job loses.
To be honest, a simple validation does not take much, it might be a simple call to the right person, a mail, or simply moving from your office to the superior's office to seek clarity. Assumption is a lazy man's thing, save from experimental procedures which has no means of validation, we are encouraged to always validate our information before making it a basis for decision making.
Lets share our thoughts on this, and also our experiences with the lazy man assumption.
