Why Having the Last Word Is So Important for Some People 

Having the last word for some people means winning the argument. Whilst this clearly isn’t always true, it is a frustrating trait that applies to more than just Wikipedia!

It is worth remembering that the person who wins the debate is not necessarily the person who shouts the loudest, or gets in the last word.

Often a person with this personality is likely to be an egomaniac or bordering on being one. An egomaniac can be defined as a person who is obsessively self-centred or egotistical.

(Have you ever been in an argument where the other won't drop it?)

Insecurity:

Somebody who lacks confidence or self-esteem may try to assert themselves in other ways, by expressing himself or herself in a forceful way.

Arrogance:

A person with extreme arrogance may genuinely not be able to accept that they might be incorrect, or that another person’s opinion is equally as valid as their own. 

Egocentricity:

Some people simply need to be the centre of attention, and will argue black is white in order to keep the spotlight. 

Power:

Having the last word can be perceived as powerful, often by people who lack assertiveness in other areas of their lives.

Anger:

Refusal to debate calmly can be a reaction to feelings of anger, and shouting down an opponent is a way to express their feelings.

Dominance:

As with power, a person who feels the innate need to dominate others or to establish their seniority may do so by insisting they have the final word in any conversation.
