2 . Having too many , or too few , Facebook friend

In a 2008   survey , Michigan State University researchers ask college student to look at fictional Facebook profiles and settle how much they liked the profile ' owner .

Results testify that the " sweet spot " for likability was about 300 protagonist . Likability rating were small when a visibility owner had only about 100 friends , and almost as low when they had more than 300 friends .

As for why 300 - plus friends could be a turning - off , the study author write , " Individuals with too many friends may come out to be focusing too much on Facebook , friending out of despair rather than popularity . "

On the other bridge player , the college students doing the evaluation each had about 300 Facebook friends themselves . So the investigator recognise that in a population where the most common number of Facebook booster is 1,000 , the sweet position for likability could be 1,000 .

Keep in mind , though , thata 2014   study foundthat the average number of Facebook friends among adult users was 338 .

Interestingly , the study also suggest   that player were n’t consciously aware that they liked people less when they had too many or too few Facebook friends .

But psychologist say   that disclosingsomething   too   intimate — say , that your sister is deliver an extramarital affair — while you ’re still get to know someone can make you seem insecure and decrease your likability .

The Francis Scott Key is to get just the correct amount of personal . Asa 2013 studyled by Susan Sprecher at Illinois State University suggests , plainly sharing inside information about your hobby and your favored puerility memories can make you seem warm and more appealing .

4 . demand someone question without let the cat out of the bag about yourself at all

That same 2013 studyby found an crucial caveat to the idea that self - disclosure predicts intimacy : It has to be mutual . mass mostly like you less if you do n’t reciprocate when they give away something internal .

In the study , unacquainted participants either engaged in back - and - forth ego - disclosure or took turns ego - disclosing for 12 minutes each while the other listened . resultant role showed that participants in the back - and - forth chemical group wish each other significantly more .

As the authors publish , " Although shy or socially anxious the great unwashed may ask doubtfulness of the other to take away attention from themselves , our inquiry shows that this is not a skilful scheme for human relationship installation . Both participant in an fundamental interaction need to disclose to generate mutual closeness and like . "

5 . post a close - up visibility photo

If your LinkedIn profile features an image of your face much smushed up against the camera , you ’d be wise to change it .

Research from California Institute of Technologysuggests   that confront photographed from just 45 cm — about 1.5 feet — away are considered less trustworthy , attractive , and competent than aspect photographed from 135 cm , about 4.5 metrical foot , aside .

6 . Hiding your emotion

Research suggest that letting your real feelings amount through is a good scheme for getting the great unwashed to like you than bottling it all up .

In one 2016 study ,   University of Oregon researchers videotape mass keep an eye on two movie scenes : the   fake - sexual climax part of   the movie " When Harry Met Sally " and a sad scene from " The Champ . " In some cases , the thespian were instructed to react by nature ; in another they were instructed to suppress their emotion .

College students then look on the four version of the video . Researchers measured how much interest the student expressed   in befriend the mass in the TV , as well as their assessments of the personalities of the people in the video recording .

Results show that suppresser were judged less likable — as well as less extroverted and agreeable — than people who emoted course .

The researcher write : " People … do not pursue close relationship at random — they probably look for people who are likely to reciprocate their investment . So when beholder observe that someone is hiding their emotions , they may read that as a disinterest in the matter that emotional formula facilitates — minginess , social support , and interpersonal coordination . "

7 . Acting too nice

It makes logical sense that the gracious and more altruistic you seem , the more people will like you . But some scientific discipline   advise otherwise .

In a 2010 study , researchers at Washington State University and the Desert Research Institute had college students play a reckoner game with four other players , who were really handling by the investigator .

Here ’s how one of the subject field authors explained the study procedure inThe Harvard Business Review :

" Each participant was lay in a five - person group , but did not see its other extremity . Each was given endowments that they could in their spell choose to keep or come back , in whole or in part . There was some incentive to maximize one ’s holding , but not an obvious one .

" ( The player were told that , at the end of the semester , a random drawing of their public figure would be held and those few who were chosen would have their holdings converted to Dining Services coupon reformable at campus eateries . ) "

Some of the fake   participants would give up wad of points and only take a few voucher — a rather altruistic   behavior . As it release out , most participants suppose they would n’t require to work with their unselfish teammate again .

In a similar , follow - up experiment in the same study , some said the unselfish teammate made them look bad ; others suspected they had subterraneous motivation .

8 . Humblebragging

In an crusade to impress booster and likely employer , some the great unwashed mask line-shooting   as self - unfavorable judgment . This behavior , otherwise have it away as " humblebragging,“could be a turn - off , according toa   recent studyfrom Harvard Business School .

In the written report , college student were require to write down how they ’d answer a question about their vainglorious impuissance in a job consultation . Results showed that more than three - quarters of participant humblebragged , normally about being a perfectionist or working too heavily .

Yet main research assistant said they ’d be more likely to lease the participant who were good , and found them significantly more likable . Those scholar tell things like , " I ’m not always the best at staying organise " and " Sometimes I overreact to situations . "

Another alternative in a job - interview situation is   totalk about weaknessesthat do n’t immediately relate to the position   — for good example , a veneration of public speaking if you ’re applying for a writing position .

9 . Getting too neural

Never lease ‘em see — or smack — you sudate . enquiry suggest that the odor of your nervous sweat may subconsciously influence the great unwashed ’s judgments of your personality .

In 2013,researchers at the Monell Chemical Senses Centerhad participant watch videos of women in everyday situations , like work in an office and take upkeep of a child . While see the videos , they whiff three kinds of sweat : sweat that someone had produced while exercise , sweat produced during a nerve-wracking position , and sudor grow during a trying situation that had been covered up with antiperspirant .

Participants were then demand to rate the adult female on how competent , sure-footed , and trusty they seemed .

solution indicate that participants rated the woman low-down on all measures when they smelled the tension - induced sudor . When they smell the stress sweat that had been covered up with antiperspirant , they rated the womanhood more positively .

10 . Not smiling

When you ’re at a networking event and meet slews   of new people , it can be hard to keep a smile plastered on your font .   Try anyway .

In   aUniversity of Wyoming subject field , nigh 100 undergraduate women looked at photos of another charwoman in one of four poses : smiling in an open physical structure post , smiling in a shut body position , not smile in an candid body locating , or not smiling in a closed in body post . Results showed that the cleaning woman in the photograph was like most when she was smiling , regardless of her physical structure situation .

More of late , investigator at Stanford University and the   University of Duisburg - Essenfound thatstudents who interacted with each other through avatars matte up more positively about the interaction when the incarnation displayed a giving grin .

incentive : Another studyfound thatsmiling when you first meet someonehelps ensure that they ’ll think back you later .

11 . Acting like you do n’t like someone

Psychologists have known for a while about a phenomenon call up " reciprocity of like " : When we consider someone like us , we tend to like them as well .

Ina 1959 studypublished In Human Relations , for model , participant were told that certain members of a group give-and-take would in all probability like them . ( These group extremity were prefer every which way by the experimenter . ) After the discussion , player betoken that the people   they   like well were the ace who supposedly like them .

More recently , investigator at the University of Waterloo and the University of Manitobafound thatwhen we bear people to take us , we act warmer toward them — thereby increase the chances that they really will like   us .   So even if you ’re not sure how a   person you ’re interacting with tone about you , act like you like them and they ’ll plausibly care you back .

If , on the other hand , you do n’t verbalise fondness for the person you ’re meeting , you could potentially rick them off .

12 . have a hard - to - pronounce name

We know : This one’sreallynot just .

But here ’s the science : A2012 study , by researchers at the University of Melbourne , the University of Leuven , and New York University , find that people with more complicated last names are evaluate more negatively .

In one experimentation included in the work , undergraduate participant record a mock paper article about a military personnel running for an upcoming local council election . Some participants read about a human with a comparatively easy - to - pronounce last name ( Lazaridis or Paradowska ) ; others read about a man with a harder - to - pronounce name ( Vougiouklakis and Leszczynska ) .

As it turns out , participants who ’d read about the humanity with the simple name said that candidate was a better primed for the political science spot than participants who ’d read about the serviceman with the more complicated name .

13 . Name - dropping

It can be influence to cite that illustrious author who graduated from your alma mater to impress your conversation mate . But the tactic can backfire .

That ’s allot to investigator at the University of Zurich . In 2009 , theypublished a papersuggesting that name - dropping wee people seem both less likeable and less competent .

For the study , University of Zurich students interact with " mate "   via email ( the emails had really been generated by the researchers ) .

In some emails , the partner mentioned that Roger Federer was his friend and that they ’d worked out together . In other emails , the cooperator only observe that Federer was a ally . In another bent of emails , the collaborator mention that he or she was a fan of Federer . And in some emails , the collaborator did n’t bring up Federer at all .

Results showed that the stronger the supposed association between the partner and Federer , the less participants liked their spouse . The research worker set up that was largely because player felt their partners were manipulative .
