This Personality Trait Cuts Alzheimer’s Risk In Half

A study of hundreds of nuns and monks reveals which trait cuts Alzheimer’s risk in half.

A study of hundreds of nuns and monks reveals which trait cuts Alzheimer’s risk in half.

Being conscientious cuts the risk of developing Alzheimer’s disease in half, research finds.

People who are conscientious tend to be more organised, responsible and in control of their impulses.

The study’s authors explain:

“Conscientiousness (eg, “I am a productive person who always gets the job done”) refers to a tendency to be self-disciplined, scrupulous, and purposeful.”

They are also more likely to follow through on their duties and obligations.

The study of hundreds of nuns and monks found that those who were more productive and reliable were less likely to be affected by Alzheimer’s.

People high on conscientiousness were also more likely to experience a slower cognitive decline with age and lower risk of mild cognitive impairment (a risk factor for Alzheimer’s).

The results come from a study of 997 elderly nuns, priests and monks, none of whom had dementia at the start of the study.

Many were followed up for more than a decade.

The brains of those that died were examined for markers of Alzheimer’s.

The study revealed that those with the highest levels of conscientiousness were at an 89% lower risk of developing Alzheimer’s compared to those with the lowest levels.

Surprisingly, the results could not be explained by conscientious people living more healthily.

Instead, the authors write that it could be partly down to education:

“…conscientiousness is a consistent predictor of academic and occupational performance.

Both level of educational and occupational attainment and the nature of occupational experiences have been associated with risk of AD.

Highly conscientious people may have a more intensive exposure to these educational and occupational experiences than less conscientious individuals and thereby derive additional benefit.”

Being conscientious may also buffer against life stress, they write:

“Conscientiousness is associated with a higher level of resilience and greater reliance on task-oriented coping.

These factors might lessen the adverse consequences of negative life events and chronic psychological distress, which have been associated with risk of dementia in old age.”

The study was published in the journal JAMA Psychiatry (Wilson et al., 2007).

The Simplest Of All Personality Tests Is Surprisingly Accurate

This easy test reveals your personality accurately.

This easy test reveals your personality accurately.

People are surprisingly accurate at judging their own personality, research finds.

Simply rating your own personality produces reasonably accurate results — certainly in line with how others likely view you.

When people judge themselves on the five basic personality traits, they are mostly accurate.

The five basic personality traits are:

  1. Openness to experience: curiosity and inventiveness.
  2. Conscientiousness: efficient and organised.
  3. Extraversion: outgoing and energetic.
  4. Agreeableness: friendly and compassionate.
  5. Neuroticism: nervous and sensitive.

Have a go at rating yourself on these factors right now — you probably won’t be far off.

Simply give yourself a score out of 10 for each of the five factors.

Scoring 5 is average, 1 is very low and 10 is very high.

Clue: most people tend towards the middle of the scale.

Dr Brian Connelly, study co-author, said:

“It’s widely assumed that people have rose-coloured glasses on when they consider their own personality.

We found that isn’t necessarily the case, that on average people don’t show any trend in rating themselves more favourably than they’re rated by their peers.”

The conclusions come from 160 different studies of personality.

The researchers were looking for evidence of self-enhancement.

Dr Connelly explained the results:

“We make personality judgements of ourselves and others all the time, and a popular notion is that self-reports are more positively biased … but we find little support for that in the literature.”

One reason people may not self-enhance is that they are kept in line by others, Dr Connelly said:

“People are generally attuned to the impressions they convey.

Some people may stray toward self-enhancement, or in the opposite direction with self-effacement, but there are social costs associated with both that makes the general trend for people to be accurate.”

Next, Dr Connelly plans to look at self-enhancement at work:

“It’s important to know if self-enhancers perform worse on the job or have more trouble in school.

It could be they don’t internalize negative information about themselves or even totally forget about it altogether, both of which could have negative outcomes.”

The study was published in the journal  Psychological Science (Kim et al., 2018).

5 Warning Signs Of A Toxic Personality

How to spot people with a toxic personality.

Toxic personalities can survive and even prosper in the workplace, and elsewhere, if they have one critical ingredient.

People with toxic personalities have a mixture of arrogance and deceitfulness.

People with toxic personalities:

  1. are willing to flatter others to obtain favours,
  2. to take advantage of others by cheating,
  3. enjoy showing off their higher status to others,
  4. act in an entitled way,
  5. and want to have things others do not.

However, toxic personalities can survive and even prosper in the workplace, and elsewhere, if they have one critical ingredient: social skills.

Social skills help those with toxic and dark personalities to hide their deceitful nature.

The toxic person continues to abuse trust and trick others behind a smokescreen of harmlessness.

Unfortunately, the study also revealed, others tend to view those who are good at office politics as ripe for promotion, despite their negative traits.

The good news for those that lack social skills is that honesty and humility are highly valued as well.

The conclusions come from research that reveals how people with dark personalities get ahead in the workplace.

Professor Gerhard Blickle, study co-author, said:

“Such personalities tend to focus on themselves all the time.

Good social skills enable them to deceive others.”

For the study, the researchers interviewed 203 small groups: each contained three people who were colleagues.

They provided data on the others about their personality and social skills.

The results showed that people who were dishonest and entitled could succeed at work if they had good social skills.

They tended to have better jobs and to be seen as more capable by their superiors.

However, those without social skills could still succeed at work with honesty and humility.

Professor Blickle said that rooting out toxic personalities means less emphasis on good impressions and more on performance:

“In order to slow down the ascent of toxic personalities, more attention should be paid to actual performance and less to the good impression when selecting staff and making assessments.

Here, it makes sense for instance to also look at the sickness and notice rate of employees, or customer loyalty.”

The study was published in the journal Personality and Individual Differences (Kholin et al., 2020).

The Personality Trait Linked To Looking Younger

People high on this personality trait look younger and are able to walk faster.

People high on this personality trait look younger and are able to walk faster.

Self-control is linked to aging more slowly, a study finds.

People who are better able to control their thoughts, feelings and behaviours have biologically younger brains and bodies at age 45.

This means that people with higher self-control look younger and are able to walk faster.

Those who find themselves somewhat lacking in self-control, though, should not despair.

Self-control is not set in stone and can be learned.

In addition, midlife is not too late to make changes like starting to exercise and quitting smoking.

The conclusions come from a study of almost 1,000 people in New Zealand who were tracked from birth.

The aim of the study was to see whether self-control helped people prepare for old age.

Dr Richmond-Rakerd, the study’s first author, explained:

“Our population is growing older, and living longer with age-related diseases.

It’s important to identify ways to help individuals prepare successfully for later-life challenges, and live more years free of disability.

We found that self-control in early life may help set people up for healthy aging.”

The people in the study were tracked from around the age of 3-years-old until they were 45.

As children their self-control was measured and as adults their brains and bodies were tested for physiological signs of aging.

The results revealed that people with higher self-control as children walked faster, had younger looking faces and healthier bodies overall as adults.

Professor Terrie Moffitt, study co-author, said:

“Everyone fears an old age that’s sickly, poor, and lonely, so aging well requires us to get prepared, physically, financially, and socially.

We found people who have used self-control since childhood are far more prepared for aging than their same-age peers.”

Improve your self-control

There are a variety of science-backed ways to improve your self-control.

These include positive affirmations, keeping busy, feeling grateful, abstract thinking, avoiding the ‘license to sin’, and not trying too hard.

The Most Socially Attractive Personality Trait

What trait people find attractive on first impression and over the long term.

What trait people find attractive on first impression and over the long term.

Optimists are seen as more socially attractive than pessimists, research finds.

But this is just when people meet for the first time and do not know each other.

In long-term relationships, optimists are best matched with other optimists and pessimists get on with both other optimists and pessimists.

In other words, optimists mix well in long-term relationships with everyone, but pessimists can be a downer on other optimists — although they don’t seem to bother other pessimists.

The results come from a study of 248 people who read a series of vignettes that described either optimistic or pessimistic people.

Most people found the optimists more socially attractive.

However, people who were themselves optimists liked the other optimist even more.

On the other hand, people who were pessimists were not quite as keen on the optimist, but still preferred them to the pessimist.

Pessimists also had a sneaky liking for the other pessimist.

The results were more nuanced, though, when people considered their own long-term relationships.

Optimists were more satisfied when in a relationship with another optimist, and pessimists were happy with another pessimist or an optimist.

The authors write:

“…optimists may perceive a pessimistic partner as a burden, which may in turn affect their perceptions of relationship quality negatively.

Interestingly, this was not the case for pessimists, who reported the same levels of relationship quality regardless of whether they perceived their partners as pessimistic or as optimistic.”

The results support a psychological theory about interpersonal attraction called the ‘similarity-attraction hypothesis’.

The study’s authors write:

“Such a similarity attraction effect has been shown to be characteristic in the field of attitudes.

The similarity-attraction hypothesis claims that people tend to perceive others who are similar to themselves as more attractive than dissimilar others.”

The study was published in The Journal of Positive Psychology (Böhm et al., 2010).

The Personality Change That Is A Dementia Warning Sign

The results showed that people whose personality changed in this way were more likely to develop dementia.

The results showed that people whose personality changed in this way were more likely to develop dementia.

Apathy is an early warning sign of dementia in people with cerebrovascular disease, research finds.

Apathy may result from damage to the brain’s white matter, which is primarily used for communication between regions of the brain.

Cerebrovascular disease occurs in around one-in-three older people and is the most common cause of vascular dementia.

Vascular dementia is the next most common type of dementia after Alzheimer’s disease, accounting for up to 10 percent of cases.

Older people who show a new lack of interest, enthusiasm or concern are at greater risk of developing dementia, the study found.

Previously it was thought that depression was a warning sign of dementia, but this study does not support that conclusion.

Mr Jonathan Tay, the study’s first author, said:

“There has been a lot of conflicting research on the association between late-life depression and dementia.

Our study suggests that may partially be due to common clinical depression scales not distinguishing between depression and apathy.”

The study included over 450 people from the UK and the Netherlands who were tracked for several years.

The results showed that people whose apathy increased over time were more likely to develop dementia.

Mr Tay said:

“Continued monitoring of apathy may be used to assess changes in dementia risk and inform diagnosis.

Individuals identified as having high apathy, or increasing apathy over time, could be sent for more detailed clinical examinations, or be recommended for treatment.”

The researchers think that similar mechanisms underlie cognition and motivation.

Mr Tay said:

“This implies that apathy is not a risk factor for dementia per se, but rather an early symptom of white matter network damage.

Understanding these relationships better could have major implications for the diagnosis and treatment of patients in the future.”

The study was published in the Journal of Neurology, Neurosurgery & Psychiatry (Tay et al., 2020).

This Trait Is A Sign Of Good Mental And Physical Health

People with this trait are more likely to be in both good psychological and good physical health.

People with this trait are more likely to be in both good psychological and good physical health.

People with a stronger sense of purpose in life are more likely to live healthily — both mentally and physically.

According to research, the reason may be that purpose in life banishes the natural conflict people experience when trying to make healthy choices.

Purpose in life can come from work, family, a sense of self or other broad aim or goal being pursued.

Feeling purposeful contributes to the feeling that life is meaningful:

  • People who feel life is meaningful are more likely to be in both good psychological and good physical health.
  • People who feel life isn’t meaningful are more likely to be depressed, to require therapy and even feel suicidal.

Dr Yoona Kang, the study’s first author, said:

“Purpose in life has been robustly associated with health in previous studies, but the mechanism through which life purpose may promote healthy living has been unclear.”

For the study, 220 people with sedentary lifestyles answered a survey that asked them how much they agreed with statements like:

  • “I have a sense of direction and purpose in my life”
  • “I don’t have a good sense of what it is I’m trying to accomplish in life.”

They were then shown messages urging them to get more exercise.

While reading these messages, their brains were scanned.

The results showed that people who had more purpose in life had less activity in brain regions related to processing conflicts.

In other words, a generalised purpose in life made people argue with the statement less.

Sure enough, they were also more likely to accept that doing a little more exercise was a good idea.

Dr Emily Falk, study co-author, said:

“We conduct studies both to understand how different kinds of health messaging can help transform people’s behaviors and why some people might be more susceptible than others.

This study does a nice job starting to unpack reasons why people who have a higher sense of purpose in life might be more able to take advantage of this messaging when they encounter it.”

The study was published in the journal Health Psychology (Kang et al., 2019).

This Personality Trait Boosts Happiness

Acting out this personality trait makes people feel happier.

Acting out this personality trait makes people feel happier.

Acting like an extravert makes people feel happier — even natural introverts, research finds.

Both extraverts and introverts report greater well-being after a week spent being more talkative, assertive and spontaneous.

It is the first study to report the benefits of acting like an extravert over such an extended period.

The study also demonstrates that people who are naturally introverted can enjoy this exercise as much as extraverts.

‘Faux’ extraverts (people who are really introverts) reported no problems acting as extraverts.

Professor Sonja Lyubomirsky, the study’s first author, said:

“The findings suggest that changing one’s social behavior is a realizable goal for many people, and that behaving in an extraverted way improves well-being.”

For the study, 123 people were asked to act like extraverts for one week and introverts for another week.

During the extravert week, participants were told to be talkative, assertive and spontaneous.

During the introvert week, they were told to be more deliberate, quiet and reserved.

People were informed that acting like an introvert and like an extravert is beneficial.

This was to try and dampen the effects of participants’ expectations.

The results showed that people felt better after a week acting as an extravert and worse after the week as an introvert.

The positive effect on well-being is the largest known among happiness interventions.

Surprisingly, acting like an extravert seems to cause people’s personality to shift in that direction.

Professor Lyubomirsky said:

“It showed that a manipulation to increase extraverted behavior substantially improved well-being.

Manipulating personality-relevant behavior over as long as a week may be easier than previously thought, and the effects can be surprisingly powerful.”

The study was published in the Journal of Experimental Psychology: General (Margolis & Lyubomirsky, 2019).
