Should we ever detect an extraterrestrial civilization , or any kind of alien life for that matter , it ’s a secure bet they ’ll bet very unlike from us . They ’ll also probably think in a means that ’s completely foreign to what we ’re used to . Here ’s how expert think we might be able-bodied to predict what the head of extraterrestrial will be like .

Late last year , I talked about howextraterrestrial intelligence service are believably more like us than not — at least for those foreign civilization living in a post - industrial Information Age . But we have no empiric grounds to underpin such a claim . It ’s potential , for example , that we ’re the anomaly when it comes to technological civilization , and that there ’s a multiplicity of alien - types that far exceeds our imagination and the limits of our current science . Perhaps it ’s 16 - tentacled rhinoceros - cephalopods living in glass noodle that ’s the norm . Or maybe intelligent minds egress from biologic computers that mold on the control surface of dynamically complex pool trash .

No doubt , alien could be really , really weird . At least liken to us . And not just in terms of their physical morphologies or cultural and technological adaptations . The very way they suppose could be immensely dissimilar from the way we do it . extraterrestrial could have substitute modes of intelligence , communicating , and societal cooperation that we can just opine .
gratefully , there are other intelligences we can study . As a new paper published in Acta Astronautica suggest , our efforts to profile nonhuman animal intelligence can help us develop unbiassed tool for key other types of word , both on Earth and beyond . What ’s more , these intelligence profiles can provide a new view on how we should look for aliens and what we might expect to find .
The Self-Sampling Bias
There may be limitation to using ourselves as the standard template for all intelligence service . As noted by marine mammal biologist / behavioural life scientist Denise Herzing , who ’s the author of the unexampled study , most of our definition of intelligence are based on comparisons of nonhuman cognitive and nomenclature power with our own .
In particular , we have a diagonal towards hierarch - like mintage , and for unspoilt reason . As high priest , we for certain appear to have something extra going on , both in terms of our forcible and intellectual capacities . But as we ’re discover , man are n’t the be - all and remainder - all of word on this planet . Differentanimals have different capability , many of which result in qualitatively different psychological and cognitive experiences . For model , as Japanese research worker have learned , chimp do better on working computer memory tests than humans .

Historically , our measures of nonhuman intelligence has looked like this :
strong-arm measurements : mental capacity to consistence ratio , brain social system / swirl / neuronic denseness , bearing of artifact and strong-arm dick
experimental and sensory measurements : centripetal sign , complexity of signals , cross - average abilities , societal complexity
Data mining : entropy hypothesis , signaling / haphazardness , design realization
Experimentation : remembering , cognition , terminology comprehension / manipulation , theory of thinker
Direct interfaces : one path and two way interface with high priest , dolphins , fowl
Accidental interactions : human / animal symbiosis , cross - species enculturation
But these are mostly “ human - like ” attributes and metre . Most scientist are often reluctant to consider other types of news that may not have human analogue .
“ [ Our ] ability to profile ‘ type ’ of intelligence that differ on a variety of shell is weak , ” writes Herzing . “ Just as biologist unfold their definition of life to look at extremophiles in strange conditions , so must we stretch our description of character of minds and begin profiling , rather than equating , other life forms we may encounter . ”
Intelligence is COMPLEX
To that ending , Herzing has proposed a new approach to profile a variety of nonhuman intelligence along multiple dimensions . Called COMPLEX ( COmplexity of Markers for Profiling Life in EXobiology ) , it face like this :
EQ : Encephalization Quotient
CS : Communication Signal complexity
IC : Individual complexness
SC : Social Complexity
II : Interspecies Interaction
For example , dolphins have a high encephalization quotient , they take in complex communication , and have cock-a-hoop learning ability . The octopus is capable of associative acquisition , tameness , and exploratory behavior . Bees have collective intelligence , a symbolic waggle terpsichore , and are capable of counting and learning . Even bacteria can present complex behavioural responses without having to develop complex brains . As for machine intelligence , namely AI , it demonstrates intelligence via neural net , computational power , and algorithms .
To scale these markers , Herzing used a little set of taxa devise by life scientist Lori Marino and Kathryn Denning . Each category was scored by experts on a scale from 1 to 10 . Using this organization , mahimahi scored high in most categories , bee and machines scored relatively high in both the Communication Signal and Social Complexity categories , and germ scored high in terms of Interspecies Interaction .
This chart shows the like class scores for each taxon . The carmine box seat indicate the most interesting vista of various taxa :
The overlapping five dimensional profiles generated a clear-cut soma for each being :
Five unlike profiling types were described :
The Party beast : Brainy , communicative , and socially interactional ( a high potency for societal interactions )
The Accountant : Brainy and particular orient ( a high-pitched potential for specialised interaction )
The Loner : Brainy , communicatory — but nonsocial ( medium potential for individual interaction )
The bunch : communicatory and integrated ( low potential for individual interaction )
The fussy Body : Detail oriented and follows sureness ( smart , but downcast potential for originative fundamental interaction .
Charted , these profiling type attend like this :
Herzing says this system can be easily used to assess a expectant pool of nonhuman intelligence .
Interestingly , her findings advise — and like I advert to in the beginning — that convergent phylogenesis may result in a certain universality of cognitive aspects of social animal , let in the power to compass artificial language ( like mammals and birds ) and show numerical competency ( such as mammals , birds , Pisces , and amphibious vehicle ) . Indeed , many of these traits often predate language product or verbal language . Though she did n’t submit this in her paper , it ’s not inordinate to suggest that word do converge around sure cognitive trait .
The Search for Alien Alien Intelligence
Moving on the issue of exobiology and SETI , Herzing says her system can also be used to assess alien nonhuman intelligence .
“ If we can successfully use design acknowledgement tools to profile ‘ intelligent type ’ on Earth , could we then enforce these test to species outside our Earth ? , ” she asks . “ Could we develop pattern recognition tools and technique that verify ‘ types ’ , for remote information gathering ? ”
She says that , based what we be intimate of extremophiles , we should expect a similar diverseness of case and manifestations of intelligence . That said , some “ types ” of organisms may utilise multiple of even strange sensory organisation .
“ Documenting the conduct of a species , as in the case of dolphins , can give us examples of quantitative measures , ” Herzing recite io9 . “ For example , by measuring such things as personality — via boldness , shyness , willingness to explore — we might develop tool to measure these qualities in other species , to find out whether they are approachable or not , either as soul or as a species . ”
So whensearching for alien lifespan , it could help us , for case , to predictbiosignaturesresident in the atmospheric composition of exoplanets , whether it be generated by microbes or an industrial - scale civilization . Or , it could inform SETI . We ’re currently take care for radio signal , but perhaps we should be count for some other kind of communicating beacon or signature produced by a civilization with sensorial , cognitive , and physical capacities different from our own .

Indeed , profiling other “ eccentric ” of intelligence on Earth would be a good physical exercise for next exobiology explorations . Such a system could prepare us for what we might find , whether it be microbic life , complex sublunar organism , or even an intelligence that ’s subject of communicating with us .
