Tommy Seymour insists the cracks in Scotland 's creaking defence have not been caused by mental weakness . The Glasgow wing angrily shot down the suggestion that psychological frailties had been the reason for the Scots ' wretched RBS 6 Nations campaign . Vern Cotter 's team strode purposefully into this year 's championships on the back of three encouraging displays against Argentina , New Zealand and Tonga in November . Some pundits even tipped the the Dark Blues as dark horses for the title . But the same old self-inflicted gaffes that have cost them dear , with Ireland now preparing to complete a miserable run by handing the Celtic neighbours their fifth straight defeat in Edinburgh this Saturday . Seymour knows his side have let themselves down - but he insist their problems do not start in the mind . Tommy Seymour has dismissed talk of mental weakness in the Scotland camp . He said : 'No - 100 per cent not . I would almost take offence to the notion of that . 'Listen , I can understand the questions that are asked because people obviously look at the performances and think there is a button here that needs to be pressed . 'But there is definitely not a mental fragility . ' The Scots kicked-off their campaign in Paris but despite notching the only try , they allowed France to kick their way to a 15-8 win following a string of penalties . Wales then took control of their second match at Murrayfield after stand-off Finn Russell was sin-binned when his 'reckless ' tackle left jumping Dragons fly-half Dan Biggar in a heap . There was more misery in store as Italy 's rolling maul steamrollered the Azzurri to a last-gasp win in the capital , while Scotland sparkled briefly at Twickenham on Saturday before the Auld Enemy fired back into a three-way shoot-out for the title by adding 15 unanswered points in the second half . 'We need to stop being the creators of our own downfall at times , ' added Seymour . 'But there is certainly no fragility on a mental aspect with any of the players I go out and play with . 'We know exactly what we can do . We are fully confident in that . There needs to be an ability within all of us that we can do these things for 80 minutes . 'But we are definitely not in a position where we are doubting our abilities . ' VIDEO England v Scotland - extended highlights . Scotland have lost all four of their Six Nations matches in this year 's competition . Ireland will now go in search of the win which will see them pip England and Wales to the Six Nations title this weekend . That leaves the Scots facing the ominous prospect that if they can not repel Joe Schmidt 's side , they will end this year 's Northern Hemisphere joust with a five-game whitewash for the third time since 2004 . In that case , it would leave Cotter open to the charge his first campaign had been a failure - but Seymour insists that assessment is too simplistic . He said : 'It 's probably too easy ( to describe this campaign as a failure ) I think . 'Let 's not beat about the bush , we have not won a game yet . A tournament is going to be defined for the mass part for a lot of people based on the back of wins or losses . Scotland end their dismal campaign against Ireland at Murrayfield on Saturday . 'Now in that case , you can say 'Well we can write this one off - it 's not been what we want . It 's been a failure ' . 'However , with this squad it has to be a learning process . It has to be the idea that we are building something that goes beyond five or six weeks . 'It started in the autumn and is building up to the World Cup - that has to be the mindset . 'There has been a lot of disappointment in the results from this tournament . However , the elements that have shown improvement can only mean that we have to progress from this . 'We have shown the flaws that we need to fix in order to go on . 'So in terms of fixtures , it 's been disappointing but it 's not been a failure in terms of the growth of the squad . If we learn from the mistakes and swallow the big pills we have had to take , then we can come off the back of it stronger . '
