PAPER Personality Resilience Following a Natural Disaster

We examine changes in the Big Six personality markers (Extraversion, Agreeableness, Conscientiousness, Emotional Stability, Openness to Experience, and Honesty–Humility) before and after the 2010/2011 Christchurch earthquakes in a longitudinal study of New Zealand residents (N =3,914). Results show remarkable stability in personality, save for one exception: Those who were affected by the earthquakes evidenced a slight decrease in Emotional Stability over the 2-year test–retest period relative to those unaffected by the earthquakes. These findings indicate that most aspects of personality are resilient following a major natural disaster. The slight decrease in Emotional Stability, however, points to a possible increase in vulnerability to depression and anxiety for those affected by the earthquakes. Our study provides important insights into a central question about stability and change in personality following major life events.

Please see how researchers are using the Big Six model and not more the Big Five model!
The Big Five model had been revealed as an incomplete and incorrect model to measure personality.

Please see also:
Examining the relationship between changes in personality and changes in depression.
Please remember:
Personality traits are highly stable in persons over 25 years old to 45 years old (the group of persons who could be most interested in serious online dating)
The key to long-lasting romance is STRICT PERSONALITY SIMILARITY.

WorldWide, there are over 5,000 -five thousand- online dating sites
but no one is using the 16PF5 (or similar) to assess personality of its members!
but no one calculates similarity with a quantized pattern comparison method!
but no one can show Compatibility Distribution Curves to each and every of its members!
but no one is scientifically proven!

The Online Dating Industry does not need a 10% improvement, a 50% improvement or a 100% improvement. It does need "a 100 times better improvement", not 100% better, 100X better The Online Dating Industry needs a very powerful algorithm like the "Teller Ulam design". In this case 100 times more powerful than actual matching algorithms.

Do you know that Personality Based Recommender Systems are the next generation of recommender systems because they perform far better than Behavioural ones (past actions and pattern of personal preferences) ?
That is the only way to improve recommender systems, to include the personality traits of their users. They need to calculate personality similarity between users but there are different formulas to calculate similarity. Recommender systems are morphing to .......... compatibility matching engines, as the same used in the Online Dating Industry since years, with low success rates until now because they mostly use the Big Five to assess personality and the Pearson correlation coefficient to calculate similarity.
The Big Five (Big 5, FFI, FFM, OCEAN model) normative personality test is obsolete. The HEXACO (a.k.a. Big Six) is another oversimplification. Online Dating sites have very big databases, in the range of 20,000,000 (twenty million) profiles, so the Big Five model or the HEXACO model are not enough for predictive purposes. That is why I suggest the 16PF5 test instead and another method to calculate similarity. I calculate similarity in personality patterns with (a proprietary) pattern recognition by correlation method. It takes into account the score and the trend to score of any pattern. Also it takes into account women under hormonal treatment because several studies showed contraceptive pills users make different mate choices, on average, compared to non-users. "Only short-term but not long-term partner preferences tend to vary with the menstrual cycle".
[Also some Psychologists began to encourage the use of other tests for the Online Dating Industry, like:
California Psychological Inventory (CPI)
The Millon Index of Personality Styles-Revised (MIPS Revised)
but my best recommendation is, of course, the 16PF5 normative personality test.
Nor the CPI nor the MIPS can outperform the 16PF5.]

If any researcher wants to be first in the "personalization arena" == Personality Based Recommender Systems, he/she should understand how to innovate in the ............ Online Dating Industry first of all!

What comes after the Social Networking wave?
The Next Big Investment Opportunity on the Internet will be .... Personalization!


Personality Based Recommender Systems and Strict Personality Based Compatibility Matching Engines for serious Online Dating with the normative 16PF5 personality test.
