As new methods, practices and codes of boundaries began to be introduced, many in Eastern Europe were said to feel themselves to be in a state of disillusionment.
The past 40 years had been a sham and, when living under such indoctrination for so long, it would be a mighty struggle for some to adapt to the new way of life.
Long-term prisoners experience this disillusionment as well when they are released from jail having spent a long period of their lives in incarceration.
Changing to life on the outside becomes too much because they've spent so long being institutionalised. Hence many re-offend just to be thrown back in jail and back to a routine they can't shake off but feel at ease with.
Same for those of a certain age who lived under the communist regimes in Eastern Europe for so long.
They hanker for the old days even though going back to them would see them being tightly-controlled by a duplicitous political regime.
Bizarre how it sounds to others, the aforementioned ex-cons and former citizens of the Iron Curtain generations have had beliefs drummed into them which subsequently became their core outlook on life - however wrong or strange others looking in from the outside may perceive them.
Cognitive dissonance is thus employed to keep the wolves of reason at bay.
Spectators of football are no strangers to the effect that core beliefs, fuelled by the aforementioned cognitive dissonance, can have.
Their team is always robbed, always scoring goals that should never be ruled out, always the victim of a dodgy decision and always in the right come Hell or high water.
We got another example of it this week - yet again it comes from those who following Rangers football club.
Regular readers will know that over the course of this year I've highlighted the many contradictions that have come from the Ibrox boardroom.
While some Rangers fans are alert to them as well, a great deal more appear to have been struck down with blind faith.
Every contradiction from Dave King and his merry men is either ignored or had some excuse conjured up to try and fob inquisitors off.
Persuading such people to at least take an investigative look for themselves falls on deaf ears.
The 'my club right and wrong' syndrome kicks in because their core belief system will not allow them to think that something could potentially send what they hold dear crashing to the floor.
After all, it's happened once before - June 2012 when the club they had supported for many years was liquidated and consigned to the history books never to add another milestone again.
The trauma that would have come with such an event was epic - it even reached the absurd point where some screamed at the media: "Why didn't you tell us this was happening?"
Alas, as pointed out many times before on this site, the few in the fourth estate that did tell were threatened, abused and smeared with lies and vitriol.
History is repeating itself with this club that plays out of Ibrox which was founded three years ago.
The core belief of 'the club can do no wrong and ins indestructible' has once again manifested itself into one that is impregnable - despite voices of caution and reason trying to point out that 'something is rotten in the state of Denmark'.
Rangers released a statement this week which had those with 20/20 minds wondering if this new club under the King regime actually knew what it was doing, while fans themselves seemed cock-a-hoop with joy on social media.
Reading it, you wonder why some in light blue are proclaiming this as being 'good times ahead'.
King, who said he had "north of £20million" to invest last March, is now reliant on loans from other people to keep his not-so-shiny toy operational.
Not to mention the money that his club owe a certain Mike Ashley - who also has the retail contract in his pocket and will get his monthly whack from that regardless if whether or not Rangers fans buy strips from the official shop.
The Nomad for the Stock Exchange that he promised to have in place within two days of winning the infamous March egm never arrived.
Rangers were kicked off the Stock Exchange as a result.
Yet the kool-aid has well and truly kicked in and Teddy Bear cult follow their master regardless.
Then again, cognitive dissonance has wielded a grip on such people before.
After all, Craig Whyte and Charles Green were once hailed as 'messiahs' - despite what those proclaiming King to be one might say now.
A couple of examples come in the form of Twitter posts by Chris Graham, one of the main players of the Rangers Supporters Trust and also formerly a director of Rangers for two days before his drawing a cartoon depicting the Muslim prophet Mohammed masturbating saw him resign.
As he said of Whyte when he arrived at Ibrox:
And despite seeing one Messiah destroy his last club, and another bring his new one to the brink of ruin, Graham and thousands like him have fallen for another snake-oil salesman in King - despite contradictions from the South African businessman that would have fans of other teams worrying were he to take an interest in owning them.
This week's statement from Rangers cited the recent court case involving the club's founder Charles Green and the last owner of the club that died, Craig Whyte being an issue with regard to joining the alternative market, ISDX.
As we saw not long after it was released, the content of this statement was dutifully gulped down by the glassy-eyed faithful - no surprise there.
However, a little bit of digging would have revealed this to be somewhat of a red herring.
After all, this was not going to happen in the short term even if the court cases were not happening. Because as the ISDX guidelines themselves state:
...Sufficient working capital is a vital component to the proper functioning of a business and the implementation of a credible business plan. Many businesses have gone into administration, not because they were unprofitable, but because they suffered from severe shortages of working capital to settle their outstanding liabilities.
ICAP Securities & Derivatives Exchange Limited (“ISDX”) does not require companies to demonstrate a history of revenue generation. Nonetheless it has certain key requirements for admission including: the provision of adequate working capital; a credible business plan; and a credible funding plan.
Applicable ISDX rule
The ISDX Growth Market – Rules for Issuers (the “Rules”) (Appendix 1, paragraph 34) require a disclosure in the admission document that: “...in the opinion of the directors having made due and careful enquiry, the working capital available to the issuer and its group will be sufficient for the period of at least twelve months following admission”.
The Guidance Note to paragraph 34 states that whilst a working capital report is not required to be submitted with application documents, ISDX may require a particular issuer (and frequently does in practice) to justify its compliance with the working capital requirement. It is a specific responsibility of a Corporate Adviser to review the adequacy of the working capital prior to admission....
The current 'Holding Company Vehicle' that currently trades out of Ibrox is not only doing so at a loss, it also has no credit line from a bank.
Lest we forget their friend Mr Ashley who, being a genuine billionaire, could help them out and ensure the club is run on a steady financial keel.
However, they have gone down the route of surviving on loans - why this was celebrated by fans is a mystery.
They would do well to ask Hearts fans about being propped up by loans.
In 1999, the Scottish Media Group poured in a considerable amount of money into the Edinburgh club.
Then-owner Chris Robinson proclaimed this as a move that would allow Hearts to 'compete with the big boys'.
Fans in maroon cheered but one lone voice piped up to point out something in the small print.
Ironically enough, those dulcet tones belonged to James Traynor - he who would end his career in print journalism on the sour note of not scrutinising the propaganda put out by Rangers which, if investigated, might have saved them from liquidation.
Traynor, with Hearts' SMG deal, did his job on this occasion and noticed that SMG had the right to convert their loan into stock after three years, or, and this is the crucial bit, demand their money back.
Robinson dismissed Traynor's wise counsel as 'scare-mongering' saying that converting the loan into stock was just a formality.
Guess what SMG did three years later?
They asked for their money back - it nearly killed Hearts off.
Vladimir Romanov stopped that from happening but would proceed to loan the club money from his bank, Ukio Bankas. Do you need to ask what happened next?.....
Hearts survived another attempt to kill it off but it was perilously close.
Thankfully, when the Romanov empire collapsed, the cognitive dissonance that Hearts fans clung to in 1999 had been discarded and they rallied round to help save the club - core belief be damned.
Which is maybe an approach those in Govan should take before the trauma that struck them in 2012 happens again.
Because prudent and careful financial management keeps a football club afloat.
But unless there's a drastic turnaround in the mindset of the kool-aid drinkers, employing cognitive dissonance to protect a core belief from something that questions it, may be something that could kill their club.
