Sergio Ramos and his over sincerity
It's generally accepted that sincerity is a virtue but not one to boast about as that would be construed as immodest and then we're faced with a very different debate. Sincerity could also be seen, in certain cases to be inopportune and offensive. It is a virtue but however if one decides to utilise the mechanism to cover up a vice or to curry favour, then we're barking up the wrong tree. For example: "Yesterday I hit someone, but I'm telling you this as I'm being transparent". Or what about Ramos' example where he confessed that he deliberately sought a yellow card in the game against Ajax: “The truth is I did, I'd be lying to you if I said otherwise".
Discretion
Yes, sincerity is a virtue, but one needs to remember when the truth can cause harm, sometimes what one doesn't see won't offend. Between telling the full truth or lying lies a happy medium, and this is known as discretion. Even in the court room, the accused can tell lies, something that is totally forbidden for those in the witness box. They swear to tell the whole truth and nothing but the truth whilst the accused don't take that particular oath.
Sincerity and suicide
What Sergio Ramos revealed to the media after the game in Amsterdam is what psychologists would call ‘sincericidio’, a mixture of sincerity and suicide. He sought a yellow card with opportunism and discretely at the time of the game when he deemed it right to do so. He also did so with the complicity of head coach Santiago Solari. Later on, Ramos felt a twinge of stupidity after boasting about his stunt and posted a message on his Twitter account contradicting his earlier comment which ruined everything. UEFA could't look the other way and the player was duly sanctioned with an additional one game ban. This episode was not as convoluted as the instance when Mourinho was on the bench but a slip of the tongue from the defender. A "sincericidio" if ever there was one.
